Finalizer methods in Java
Finalizer methods are almost the opposite of constructor methods. A constructor method is used to initialize an object, while finalizer methods are called just before the object is garbage-collected and its memory reclaimed. The syntax of the finalizer method is simply finalize(). The Object class defines a default finalizer method. To create a finalizer method, override the finalize() method using the following signature: [Read more…] about Finalizer methods in Java
Java Program Vowel or Not Example
In the switch statement, since same statements has to be executed corresponding to different cases (‘a’, ‘e’, ‘i’, ‘o’, ‘u’, ‘A’, ‘E’, ‘I’, ‘O’, ‘U’) so we write the statements with the last case. The break statement causes the switch statement to terminate when any of the vowels is entered. [Read more…] about Java Program Vowel or Not Example
Program To Show Importance of Continue Statement? Java Example
In this example, the continue statement is placed in the body of inner for loop. While executing inner for loop, if the condition (m==n) evaluates to true then the continue statement is executed and the remaining statement for displaying values of m and n is skipped and control is transferred to the increment expression (n++) of inner for loop. This increments the value of n by 1 and test condition (n<=2) is evaluated again for this incremented value of n. This process continues. We have used continue statement in this program so that the same value of m and n should not be displayed. [Read more…] about Program To Show Importance of Continue Statement? Java Example
Java Calculate The Sum Of Only The Positive Numbers. Example
This example computes the sum of positive numbers input by the user. When a negative number is input, the condition (num<0) become true and break statement is executed which leads to the termination of the while loop and the next statement following the loop is executed which displays the sum of positive numbers. The condition of the while loop always remains true as we have specified a non-zero value 1 which makes it run infinitely. The only way to exit this loop is to. use break statement.

Java Nested For Loop Examples
Like the nesting of if and other looping statements, the for loop can also be nested. In other words, we can have a for loop in the body of other for loop. There is no restriction on the level of nesting of loops but one should take care while nesting at multiple levels otherwise unexpected results may arise.

Solve Equation 3*x*x – 2*x +1 in Java Example
In this example, we input the interval values a and b. Each time loop is executed the value of fx is calculated and displayed on the screen for the value of x which ranges from a to b. On each iteration, x is incremented by 0.05. This continues until x is less than equal to the value of b that user inputs. [Read more…] about Solve Equation 3*x*x – 2*x +1 in Java Example
Java Program to Find Average of N Numbers
In this example, we input number of elements n (i.e.) whose average is to be calculated. When for loop begins executing, the loop control variable i is declared and initialized to 1. Then the test condition (i<=n) is checked. As it is true in this case because (1<=5) and the statements in the body of the loop are executed which inputs the first number (5 in our case) and add this value to variable sum. Then the increment expression i++ increases the value of variable i by 1 (i+ 1=2). After one complete iteration, the test condition in the for loop is checked again which is true again as (2<=5) and the body of the loop is executed again. This process continues until the loop control variable (i) is incremented to 6. Now when the test condition (6<=5) is evaluated again it becomes false and the execution of for loop terminates and control transfers to the next statement following the for loop that calculates the average of n (5) numbers which is then displayed.

Sum of First N Natural Numbers in Java Example
In this example, the sum of first 10 natural numbers is displayed. First, input the value of n (10 in this case) i.e. number of natural numbers whose sum is to be calculated. Then, after initializing the variables i to 1 and sum to 0, we enter the do-while loop. The execution of the body of loop continues as long as condition (i<=n) evaluates to true. When variable 1’s is value becomes 11, the condition becomes false and this terminates the do-while loop and program execution continues with the next statement after the loop which displays the sum of first 10 natural numbers.

Sum of Digits of a Number in Java Example
In this program, we first input the number (Say num = 12345). Next the control reaches the while loop where it checks the condition (num>0) which is true as (12345>0) so the body of the loop is executed. [Read more…] about Sum of Digits of a Number in Java Example
Math.random() in Java Example
The Random class provides a template for the creation of random number generators. The Math.random() method provides a static function for the generation of random double values. [Read more…] about Math.random() in Java Example
currentTimeMillis() Java Example
The currentTimeMillis() method returns the current time in milliseconds since 00:00:00,January I, 1970.This method is used to know the time interval a process or job takes to perform. We record the time before and after the operation and the difference of two timings tells us the total time the operation took. [Read more…] about currentTimeMillis() Java Example
Date Format Example in Java
We can change the format of the date in two steps: First, we create a formatter with the getDateInstance method. Then, we invoke the format method, which returns a String containing the formatted date. [Read more…] about Date Format Example in Java
Print System Date and Time in Java Example
The Calendar class is an abstract class used to convert dates. We can use this class to convert a Date object to fields, such as YEAR, MONTH, HOUR, and so on. We can also use these fields to update a Date object. [Read more…] about Print System Date and Time in Java Example
Java Example to translate the word in piglatin
In “PigLatin” a word such as KING is replaced by INGKAY and TROUBLE is replaced by OUBLETRAY and so on. The first vowel of the original word becomes the start of the translation, any proceeding letters being shifted towards the end and followed by AY words that begin with vowels are left on changed.

Nested For Loop in Java Example
Nested loop means one loop inside the other. When a loop is written inside the other loop, a condition is essential to maintain: the inner loop will not cross the boundary of the outer loop. That is, the inner loop will begin and end inside the outer loop. We can have any number of loops one inside the other. [Read more…] about Nested For Loop in Java Example
