Question

I try to use Math.reverseBytes in Java but giving error : The method reverseBytes() is undefined for the type Math

As you know it is static type . Why cant i use it?

import java.lang.Integer;

public class Test {
    public static void main(String[] args) {
        int x = Math.reverseBytes();//Eclipse cannot reach this function
    }
}

From Java Doc – Some Information

reverseBytes

public static int reverseBytes(int i);

Returns the value obtained by reversing the order of the bytes in the two’s complement representation of the specified int value.

Returns:
the value obtained by reversing the bytes in the specified int value.

Since:
1.5

Answer 1

There IS no “Math.reverseBytes()”.

Integer.reverseBytes() or Short.reverseBytes(), yes. Math – no.

PS:

You should definitely install JavaDoc in your Eclipse. Here’s how:
