Usage

From source file:Main.java

public static void main(String args[]) {
    boolean booleanValue = true;
    System.out.printf("boolean = %s\n", String.valueOf(booleanValue));

}

From source file:Main.java

public static void main(String[] argv) throws Exception {
    // Use String.valueOf()
    String s = String.valueOf(true);
    s = String.valueOf((byte) 0x11);
    s = String.valueOf((byte) 0xFF);
    s = String.valueOf('a');
    s = String.valueOf((short) 123);
    s = String.valueOf(123);// w  w  w  .  j  a  v a  2s .  c om
    s = String.valueOf(123L);
    s = String.valueOf(1.23F);
    s = String.valueOf(1.23D);

    // Use +
    s = "" + true;
    s = "" + ((byte) 0x12);
    s = "" + ((byte) 0xFF);
    s = "" + 'a';
    s = "" + ((short) 123);
    s = "" + 111;
    s = "" + 111L;
    s = "" + 1.11F;
    s = "" + 1.11D;
}

From source file:Main.java

public static void main(String[] args) {
    char[] data = { 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j' };

    String text = String.valueOf(data);
    System.out.println(text);/*from w w  w.  ja  va 2  s  .co  m*/

    text = String.copyValueOf(data, 3, 5);
    System.out.println(text);
}

From source file:Main.java

public static void main(String args[]) {

    long longValue = 10000000000L; // L suffix indicates long
    System.out.printf("long = %s\n", String.valueOf(longValue));
}

From source file:Main.java

public static void main(String args[]) {

    double doubleValue = 3.3; // no suffix, double is default
    System.out.printf("double = %s\n", String.valueOf(doubleValue));
}

From source file:Main.java

public static void main(String args[]) {

    float floatValue = 2.5f; // f indicates that 2.5 is a float
    System.out.printf("float = %s\n", String.valueOf(floatValue));
}

From source file:Main.java

public static void main(String[] args) {
    Arrays.asList(1, 20, 40, 4).stream().filter(n -> n < 30).map(n -> "number: " + String.valueOf(n))
            .forEach(n -> System.out.println(n));
}

From source file:Main.java

public static void main(String args[]) {
    Object objectRef = "hello"; // assign string to an Object reference
    System.out.printf("Object = %s\n", String.valueOf(objectRef));

}

From source file:Main.java

public static void main(String args[]) {
    char charArray[] = { 'j', 'a', 'v', 'a', '2', 's', '.', 'c', 'o', 'm' };
    System.out.printf("char array = %s\n", String.valueOf(charArray));

}

From source file:Main.java

public static void main(String[] args) {
    MyEnum enum1 = MyEnum.Choice1;
    System.out.println("enum1==>" + String.valueOf(enum1));
    MyEnum enum2 = MyEnum.getByValue(enum1.getValue());
    System.out.println("enum2==>" + String.valueOf(enum2));
    MyEnum enum3 = MyEnum.getByValue(4);
    System.out.println("enum3==>" + String.valueOf(enum3));
