Transpose Matrix in java

A matrix which is formed by turning all the rows of a given matrix into columns and vice-versa. The transpose of matrix A is written A^T.


public class TransposeMatrix {

public static void metrix(int[] arr, int j)
{
for(int i=0;i<arr.length;i++)
{
if((i+1)%j==1)
{
System.out.println();
}
System.out.print(" "+arr[i]);
}
System.out.println(" transpose matrix");


}
public static void main(String[] args)
{
int [] a={1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16};
int j=2;

metrix(a,j);
}

 }


Output :
1 2
 3 4
 5 6
 7 8
 9 10
 11 12
 13 14
 15 16 transpose matrix
