String literals vs String Object in Java

In java, a String can be created in two ways, given below.

  • String foo="Test";
  • String fooobj=new String("Test");

Everywhere is mentioned the difference between the two ways to create a String. I want to learn more about What is the appropriate scenario, where should we go for

  String foo="Test";

And when to go after

 String fooobj=new String("Test");  ?

Short answer: if in doubt, you do not want new String("literal here"). If you need it, you will find out what you need and why.

Long answer:

public static final String MARKER = new String("Marker");
public void someFictionalMethod(String arg) {
    if (arg == MARKER) {
        // Take action on the marker
    }
    else {
        // Take action on the string
    }
}
