Correct method form

This code does not compile.

public class Diamond {
 public static void diamondOfAsterisks(String * ) {
        for (int i = 1; i < 10; i += 2) {
          for (int j = 0; j < 9 - i / 2; j++)
            System.out.print(" ");

          for (int j = 0; j < i; j++)
            System.out.print("*");

          System.out.print("\n");
        }

        for (int i = 7; i > 0; i -= 2) {
          for (int j = 0; j < 9 - i / 2; j++)
            System.out.print开发者_开发知识库(" ");

          for (int j = 0; j < i; j++)
            System.out.print("*");

          System.out.print("\n");
        }
      }
    }

Thanks

Just remove the "arguments" of your method:

public static void diamondOfAsterisks() {
    ....

public static void diamondOfAsterisks(String * )

That won't compile! Use a valid identifier such as star or asterisk

The answer is this won't compile...

public static void diamondOfAsterisks(String * ) {

C++ Pointers convention don't apply in java...
