I can not react to Math.reverseBytes in Java

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

The Javadoc you cite for the Math class does not exist. Not a real question. — user207421, Dec 04 '12 at 09:13
You are looking for `Integer.reverseBytes(int i)`, therefore use `int x = Integer.reverseByte( yourIntValue )` — fredt, Dec 04 '12 at 12:52

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:

How do I add the Java API documentation to Eclipse?

This method does not exist in Math package.
in your code you have imported java.lang.Integer, so did you mean

Integer.reverseBytes()

?
