Question

Given the following processing array declaration with initialisation:

int[][] foo = {{1,2,3,4,5},{2,3,4,5,6},{3,4,5,6,7},{4,5,6,7,8}};

Write a loop that will modify  foo so it instead contains the values {{1,4,9,16,25},{4,9,16,25,36},{9,16,25,32,49},{16,25,32,49,64}}.

Answer 1

Solution:

public class Main
{
   public static void main(String[] args) {
   int[][] foo = {{1,2,3,4,5},{2,3,4,5,6},{3,4,5,6,7},{4,5,6,7,8}};
int [][]zoo={{1,4,9,16,25},{4,9,16,25,36},{9,16,25,32,49},{16,25,32,49,64}};
//updating the values of the array foo
for(int i=0;i<4;i++)
{
for(int j=0;j<5;j++)
{
foo[i][j]=zoo[i][j];
}
}
//printing the values of the array
for(int i=0;i<4;i++)
{
for(int j=0;j<5;j++)
{
System.out.print(foo[i][j]);
System.out.print(" ");
  
}
System.out.println();
}

      
   }
}
