What is the difference between the underlying two String objet creation.

public class pa{
public static void main(String args[]){
String s1="Sachin";
String s2=new String("Sachin");

}
}

[Ken Blair]

One uses the literal pool, the other forces a new instance to be created.

[Aum Tao]

s1 == s2; // false

s1.equals(s2); // true

[samir Sadiki]

   
public class Pa{
public static void main(String args[]){
String s1="Sachin";
String s2=new String("Sachin");
String s3=s2.intern();

System.out.println(s1 == s2);  //false
System.out.println(s1 == s3);  //true
System.out.println(s2 == s3);  //false
}
}

Adding to what previous posters have written, whenever I see something like

new String("Sachin")

in Java code, I'm inclined to assume that either:

1. The programmer is new to Java and doesn't know that they can simply write "Sachin", or...

2. Some horrible hack involving the string pool or equality versus identity is about to be attempted.

Either way, my spidey senses are tingling.
