New to Java

Hi All,

As per my understanding String equals matches the value of String and "==" matches objects represented on either side of the operator. but I saw some strange behavior while playing with these String API's.

class StringTest1
{
public static void main(String[] args)
{
String ja = "Ja";
String va = "va";

String java2 = "Java";
String java1 = ja + va;
//String java1 = "Java";

System.out.println("equals: " + (java1.equals(java2)));
System.out.println("==: " + (java1 == java2));
}
}

For the above code I get output as "true" for the first and "false" for the second expression. output of equals is fair enough but for "==" operator its giving false which as per my thinking should be true as the funda of String pooling says NO TWO STRINGS WITH SAME VALUES.
Among the 2 variables java2 is a string "Java" and java1 is a result of concatenation smthing like "Ja" + "va".

I tried to do something like
System.out.println("obj1: " + java1.hashCode());
System.out.println("obj1: " + java2.hashCode());
btu that returned the same value.

Please help me understand how come the expression be false for "==".
