Object to String Helper
Google Guava is a java library with lot of utilities and reusable components.
This requires the library guava-10.0.jar to be in classpath.
The following example shows using Objects.toStringHelper() API.
package com.bethecoder.tutorials.guava.base_tests; import java.util.Date; import com.bethecoder.tutorials.guava.common.Student; import com.google.common.base.Objects; public class Object2StringHelperTest { /** * @param args */ public static void main ( String [] args ) { Student student = new Student ( "Sriram" , 2 , "Chess" ) ; String str = Objects.toStringHelper ( student ) .toString () ; System.out.println ( str ) ; str = Objects.toStringHelper ( student ) .add ( "name" , student.getName ()) .toString () ; System.out.println ( str ) ; str = Objects.toStringHelper ( student ) .add ( "name" , student.getName ()) .add ( "age" , student.getAge ()) .toString () ; System.out.println ( str ) ; str = Objects.toStringHelper ( student ) .add ( "name" , student.getName ()) .add ( "age" , student.getAge ()) .addValue ( new Date ()) .toString () ; System.out.println ( str ) ; } }
Student{}
