Swap Elements of an Array in Java Example

Algorithm for Swap Elements of an Array:

step 1: read y

step 2: create two integer arrays a[],b[] of size y

step 3: initialize x=0

step 4: repeat through step-6 while (x < a.length)

step 5; read b[x]

step 6: x=x+l

step 7: reset x=0

step 8: repeat through step-11 while (x < a.length)

step 9: print a[x]

step 10: print one space

step 11: x=x+l

step 12: Reset x=0

step 13: repeat through step-15 while (x< y)

step 14: interchange a[x],b[x]

step 15: x=x+1

step 16: Exit

Here is the Java Example for Swap Elements of an Array:

import java.util.Scanner; 
 public class SwapArray 
 { 
                  public static void main(String args[]) 
            { 
                      int x,y; 
                      Scanner s1=new Scanner(System.in); 
                      System.out.print("Enter the Size of Array : "); 
                      y=s1.nextInt(); 
                      int a[]=new int[y]; 
                      int b[]=new int[y]; 
                      System.out.println("\nEnter The Elements In First Array\n"); 
                            for(x=0;x<a.length;x++) 
                                  a[x]=s1.nextInt(); 
                                  System.out.println("\nEnter The Elements In Second Array\n"); 
                                  for(x=0;x<b.length;x++) 
                                  b[x]=s1.nextInt(); 
                                  System.out.print("The Elements of First Array : "); 
                                  for(x=0;x<a.length;x++) 
                                      { 
                                          System.out.print(a[x]+" "); 
                                      } 
                                          System.out.print("\nThe Elements of second Array : "); 
                                  for(x=0;x<b.length;x++) 
                                      { 
                                          System.out.print(b[x]+" "); 
                                      } 
                                          System.out.print("\n"); 
                                  for(x=0;x<y;x++) 
                                     { 
                                          a[x]=a[x]+b[x]; 
                                          b[x]=a[x]-b[x]; 
                                          a[x]=a[x]-b[x]; 
                                      } 
                                          System.out.println("\nAfter swaping the Output is \n"); 
                                          System.out.print("The Elements of First Array : "); 
                                  for(x=0;x<a.length;x++) 
                                     { 
                                          System.out.print(a[x]+" "); 
                                     } 
                                          System.out.print("\nThe Elements of second Array : "); 
                                  for(x=0;x<b.length;x++) 
                                    { 
                                          System.out.print(b[x]+" "); 
                                    } 
                                          System.out.print("\n"); 
               } 
 }
