Usage

From source file:Main.java

public static void main(String[] args) {
    String s1 = String.valueOf('C'); // s1 has "C"
    String s2 = String.valueOf("10"); // s2 has "10"
    String s3 = String.valueOf(true); // s3 has "true"
    String s4 = String.valueOf(2014); // s4 has "2014"
}

From source file:Main.java

    long l = 100000;
    float f = 3.4f;
    double d = 500.99;

    System.out.println("b = " + String.valueOf(b));
