A CONCRETE EXAMPLE
Learn with questions
you might actually face
What will this Java code output?
String a = new String("test");
String b = new String("test");
System.out.println(a == b);
System.out.println(a.equals(b));
○ true / true
○ true / false
● false / true
○ false / false
a == b compares memory references, so false.
a.equals(b) compares content, so true.
== vs equals()
Understand the difference between reference comparison and content comparison with concrete examples.
