Question

Apparently there is a method that takes a char and returns a char: http://download.oracle.com/javase/6/docs/api/java/lang/Character.html#toLowerCase(char)

But I can’t seem to get it to work. My code:

import java.lang.Character;

public class Test {
    public static void main(String[] args) {
        char c = 'A';
        c = toLowerCase(c);
        System.out.println(c);
    }
}

When I compile this, I get the following error:

$ javac Test.java
Test.java:6: cannot find symbol
symbol  : method toLowerCase(char)
location: class Test
        c = toLowerCase(c);
            ^
1 error

What am I doing wrong? Thanks.

Answer 1

toLowerCase is a static method, as such you need to qualify it with the class it belongs to, as

Character.toLowerCase(c);
