All about Strings

public class StringTest {
public static void main(String[] args) {
String str1 = new String("Pragya");
String str2 = new String("Pragya");
String str3 = str1;
String str4 = "Sumit";
String str5 = "Sumit";

System.out.println(str1 == str2);
System.out.println(str1 == str3);
System.out.println(str1.equals(str2));
System.out.println(str4 == str5);
System.out.println(str4.equals(str5));

}
}

Output :
false
true
true
true

In String class, equals() method has been overridden to compare the value of String, so it compares the String data and not the memory location.
