Error ']' excpected in 2D Array Java Program

I am trying this code .But everytime it is giving me this error on compiling

Printdiagonal.java:21: error: ']' expected

System.out.println(a[j,temp]);

^

Printdiagonal.java:21: error: ')' expected

System.out.println(a[j,temp]);

^

Printdiagonal.java:21: error: illegal start of expression

System.out.println(a[j,temp]);

Java Code:

class Printdiagonal
{

                public static void main(String...s)
                        {
                        Printdiagonal P=new Printdiagonal();
                P.print(new int[][] {{1,567,4,3,33},{0,333,677,34243,8987,3434,324},{446,876,23,546565,332}});
                        }

void print(int [][]a)

        {
        for(int i=0;i<a.length;i++)
                {int temp=0;
                
                temp=i;
                while(temp>=0)
                        {
                        for(int j=0;j<=i;j++)
                                {
                                System.out.println(a[j,temp]);
                                temp--;
                                }
                        }
                }
        }
