Given a string str, the task is to check if this string is null or not, in Java.
Input: str = null Output: True Input: str = "GFG" Output: False
- Get the String to be checked in str
- We can simply compare the string with Null using == relational operator.
if(str == null)

Below is the implementation of the above approach:
Is string [GeeksforGeeks] null? false Is string [null] null? true
