Document

Gets the toString of an Object returning an empty string ("") if null input.

 ObjectUtils.toString(null)         = "" ObjectUtils.toString("")           = "" ObjectUtils.toString("bat")        = "bat" ObjectUtils.toString(Boolean.TRUE) = "true"

Usage

From source file:MainClass.java

public static void main(String[] args) {
    //Create ObjectUtilsTrial instance
    MyClass one = new MyClass();
    MyClass two = one; //Same Reference
    MyClass three = new MyClass(); //New Object
    MyClass four = null;// w  ww  .j a va2  s.  c  o m

    //Pass null get empty string
    System.out.print("6) Pass null and get back an Empty string >>>");
    System.out.println("**" + ObjectUtils.toString(null) + "**");

}

From source file:ObjectUtilsTrial.java

public static void main(String[] args) {
    // Create ObjectUtilsTrial instance
    String one = new String();
    String two = one; // Same Reference
    String three = new String(); // New Object
    String four = null;/*ww w.j a v a 2 s .  c om*/

    // four is null, returns DEFAULT
    System.out.print("1) If null return DEFAULT >>>");
    System.out.println(ObjectUtils.defaultIfNull(four, "DEFAULT"));

    // one and two point to the same object
    System.out.print("2) References to the same object >>>");
    System.out.println(ObjectUtils.equals(one, two));

    // one and three are different objects
    System.out.print("3) Check object references and not values >>>");
    System.out.println(ObjectUtils.equals(one, three));

    // toString method gets called
    System.out.print("4) toSring gets invoked >>>");
    System.out.println(one);

    // Object details displayed..toString is not called
    System.out.print("5) Display object details >>>");
    System.out.println(ObjectUtils.identityToString(one));

    // Pass null get empty string
    System.out.print("6) Pass null and get back an Empty string >>>");
    System.out.println("**" + ObjectUtils.toString(null) + "**");
