Comparing strings in java

Question

String string1 = \"Hi there\";
String string2 = \"Hi\";
String string3 = \"Hi\";

System.out.println(string1.substring(0, string2.length()) == string2); //1
System.o         


        

Answer 1

The == compare the reference - the address of the string not the value of it. For comparing strings you should use equals. The JVM will handle new String objects, so if an object of the same value exists (string2 vs string3) it might reference the same one.
