Right Angled Triangle in Java Example

by Dinesh Thakur Category: Control Structures

Algorithm for Right Angled Triangle:

step 1: Set i= 0,j 0, row=0,osc=0,var=0

step 3: Move to new line

step4: If (row>O) then execute following steps else goto step-23

step 5: Initialize isc=0

step 6: Print “*”

step 7: Initialize i=2

step 8: Repeat through step-17while (i<row)

step 9: Print “*”

step l0: Initialize j=isc

step 11: Repeat through step-13 while(j>0)

step 12: Print one space

step 13: j=j-1

step 14: Print “*”

step 15: isc=isc+ 1

step 16: osc=osc-1

step 17: I=i+ 1

step 18: If(row!=1then execute following steps else goto step-23

step 19: Initialize l=1

step 20: Repeat through step-22 while (l<=row)

step 21: Print “*”

step 22:l=l+1

step 23: Exit

Here is the Java Example for Right Angled Triangle:

```import java.util.*;

class RightAngledTriangle

{

public static void main(String s[])

{

int i,j,row,isc,osc,var;

i=j=row=osc=var=0;

System.out.print("Enter number of Rows : ");

System.out.println("\n");

if(row>0)

{

System.out.print("\t");

isc=0;

System.out.println("*");

for(i=2;i<row;i++)

{

System.out.print("\t");

System.out.print("*");

for(j=isc;j>0;j--)

System.out.print(" ");

System.out.println("*");

isc++;

osc--;

}

if(row!=1)

{

System.out.print("\t");

for(int l=1;l<=row;l++)

System.out.print("*");

}

}

System.out.println("");

}

}

```
