Java-Buddy

Example of Comparing Strings in Java:

package javaex_cmpstring;
/**
 * @web http://java-buddy.blogspot.com/
 */
public class JavaEx_CmpString {
 
 String s1 = new String("java-buddy");
 String s2 = new String("java-buddy");
 String s3 = "java-buddy";
 String s4 = "java-buddy";
 String s5 = "java-" + "buddy";
 //s3, s4, and s5 will reference to the same object of "java-buddy"
 public static void main(String[] args) {
 new JavaEx_CmpString().CmpString();
 }
 
 private void CmpString(){
 System.out.println("s1==s2: " + String.valueOf(s1==s2));
 System.out.println("s3==s4: " + String.valueOf(s3==s4));
 System.out.println("s1==s3: " + String.valueOf(s1==s3));
 System.out.println("s3==s5: " + String.valueOf(s3==s5));
 
 System.out.println("s1.equals(s2): " + s1.equals(s2));
 System.out.println("s3.equals(s4): " + s3.equals(s4));
 System.out.println("s1.equals(s3): " + s1.equals(s3));
 System.out.println("s3.equals(s5): " + s3.equals(s5));
 
 }
}
