String class valueOf method example.

String class valueOf method example:- This example demonstrates the working of valueOf method. 
this method returns String representations of all data types values

Syntax:-valueOf(boolean b) 


Here is the code:-
/**
 * @(#) ValueOfString.java 
 * ValueOfString class demonstrates the working of valueOf() method of String class of lang package
 */


public class ValueOfString {
  public static void main(String args[]) {

    // method converts any data type value in to String type
    boolean result = true;
    int in = 234;
    char ch = 'u';
    double dou = 34.86;
    float flt = 54.889f;

    System.out.println("String represented boolean value:  "
        + String.valueOf(result)
        + "\nString represented integer value:  " + String.valueOf(in)
        + "\nString represented char value:  " + "'"
        + String.valueOf(ch) + "'"
        + "\nString represented double value:  " + String.valueOf(dou)
        + "\nString represented float value:  " + String.valueOf(flt));

  }
}
Output of the program:-
---------------------------------------
String represented boolean value:  true
String represented integer value:  234
String represented char value:  'u'
String represented double value:  34.86
String represented float value:  54.889
