Java String isEmpty()
The syntax of the string isEmpty() method is:
string.isEmpty()
Here, string is an object of the String class.
isEmpty() Parameters
The isEmpty() method does not take any parameters.
isEmpty() Return Value
- returns true if the string is empty (length is 0)
- returns false if the string is not empty
Example: Java String isEmpty()
class Main {
public static void main(String[] args) {
String str1 = "Java Programming";
String str2 = "";
System.out.println(str1.isEmpty()); // false
System.out.println(str2.isEmpty()); // true
}
}
Note: A non-initialized string is not an empty string. If you use isEmpty() on a string that is not initialized, you will get an error.
