Question

What are the values in arrays a, b, and c after the following code executes (list all of the elements of the arrays)?

double[] a = new double[4];

double[] b = {6,4,2};

a[a.length-1] = b[b.length-1];

double[] c = b;

c[0] = -1;

b[1] = c[2];

c = a;

c[0] = -2;

a[1] = c[3];

Answer 1

Please find the updated code below:::

package classes10;

public class Main {
   public static void main(String[] args) {
       double[] a = new double[4];
       double[] b = {6,4,2};
       a[a.length-1] = b[b.length-1];
       double[] c = b;
       c[0] = -1;
       b[1] = c[2];
       c = a;
       c[0] = -2;
       a[1] = c[3];
      

       System.out.println("Content of array a is : ");
       for(int i=0;i<a.length;i++){
           System.out.print(a[i]+" ");
       }
      
       System.out.println(" Content of array b is : ");
       for(int i=0;i<b.length;i++){
           System.out.print(b[i]+" ");
       }
      
       System.out.println(" Content of array c is : ");
       for(int i=0;i<c.length;i++){
           System.out.print(c[i]+" ");
       }
   }
}

output:
