Two D array structure

[DMarsh12]

i have a project due tomm and am really in a pickle...i can't seem to configure the array to display just the diagnols are the corners...

here is the output im currently getting...

1 2 3
4 5 6
7 8 9


5

3 5 7
1 5 9
1 3 7 9

the first two outputs are right but i need it to be:
(xs are blank spaces)
1x3
xxx
7x9

and

1xx
x5x
xx9

and

xx3
x5x
7xx

what am i doing wrong?

public class Project3 {

    public static void main(String[] args) {
    	int a [][] = {{1, 2, 3} , {4, 5, 6} , {7, 8, 9}};
    	All(a);
    	Center(a); 		//5
    	DiagRight(a);  // 3, 5, 7
        DiagLeft(a);
        Corner(a);
    }

    public static void All(int [][] x) {
    	for (int R=0; R<=2; R++) {
    		for (int C=0; C<=2; C++) {
    			System.out.print(x[R][C] + " ");
    		}
    		System.out.println(" ");
    	}
    }

    public static void Center(int [][] x){

    	for (int R=1; R<2; R++) {
    		for (int C=1; C<2; C++) {
    			System.out.println(" ");
    			System.out.print(x[R][C] + " ");
    		}
    		System.out.println(" ");
    	}
    }

    public static void DiagLeft(int [][] x){

    	System.out.println(" ");

    	for (int R=0; R<=2; R++){
    		for (int C=0; C<=2; C++) {
    			if(R==C) {
    			System.out.print(x[R][C] + " ");
         	}
       }
    }
    }

    public static void DiagRight(int [][] x){

    	System.out.println(" ");

    	for (int R=0; R<=2; R++){
    		for (int C=0; C<=2; C++) {
    			if(R == 1 && C == 1 || R == 2 && C == 0 || R == 0 && C == 2) {
    			System.out.print(x[R][C] + " ");
         	}
       }
    }
    }

    public static void Corner(int [][] x){

    	System.out.println(" ");

    	for (int R=0; R<=2; R++){
    		for (int C=0; C<=2; C++) {
    			if(R != 1 && C != 1) {
    			System.out.print(x[R][C] + " ");
         	}
       }
    }
    }

}

public static void DiagRight(int [][] x){

    System.out.println(" ");

    for (int R=0; R<=2; R++){
        for (int C=0; C<=2; C++) {
            if(R == 1 && C == 1 || R == 2 && C == 0 || R == 0 && C == 2) {
                System.out.print(x[R][C] + " ");
            }[color=blue] else {
                // figure out what you should print if you are
                // *not on the diagonal*
            }[/color]
        }
        [color=blue]// Don't forget a newline[/color]
    }
}

Also, fix the variable and method names. These start with a lowercase letter in Java.
