How do I convert primitive data types into String?

There are times when we want to convert data from primitive data types into a string, for instance when we want to format output on the screen or simply mixing it with other string. Using a various static method String.valueOf() we can get a string value of them.

Here is the code sample:

package org.kodejava.lang;

public class StringValueOfExample {
    public static void main(String[] args) {
        boolean b = false;
        char c = 'c';
        int i = 100;
        long l = 100000;
        float f = 3.4f;
        double d = 500.99;

        String u = String.valueOf(b);
        String v = String.valueOf(c);
        String w = String.valueOf(i);
        String x = String.valueOf(l);
        String y = String.valueOf(f);
        String z = String.valueOf(d);
    }
}

When called with boolean argument the String.valueOf() method return true or false string depending on the boolean argument value. When called with char argument, a 1 length sized string returned.

For int, long, float, double the results are the same as calling Integer.toString(), Long.toString(), Float.toString() and Double.toString() respectively.
