What is the output of the following code snippet? String str1 = "Java"; String str2 = new String("Java"); System.out.println(str1 == str2);
Question
What is the output of the following code snippet?
String str1 = "Java";
String str2 = new String("Java");
System.out.println(str1 == str2);
Solution
The output of the code snippet will be "false".
Here's why:
In Java, using the "new" keyword guarantees that a new object is created in the heap memory. So, "str2" is a different object from "str1".
When you compare "str1" and "str2" using the "==" operator, it checks whether they refer to the exact same object, not whether they have the same value. Since "str1" and "str2" are different objects, the result is "false".
If you wanted to compare the values of "str1" and "str2", you should use the ".equals()" method, like so: "str1.equals(str2)". This would return "true" because the values of "str1" and "str2" are both "Java".
