The length()
method returns the length of the string.
Example
class Main {
public static void main(String[] args) {
String str1 = "Java is fun";
System.out.println(str1.length());
}
}
// Output: 11
length() Syntax
The syntax of the length()
method is:
string.length()
Here, string is an object of the String
class.
length() Parameters
- The
length()
method doesn't take any parameters.
length() Return Value
- The
length()
method returns the length of the given string.
The length is equal to the number of char
values (code units) in the string.
Example: Java String length()
class Main {
public static void main(String[] args) {
String str1 = "Java";
String str2 = "";
System.out.println(str1.length()); // 4
System.out.println(str2.length()); // 0
System.out.println("Java".length()); // 4
System.out.println("Java\n".length()); // 5
System.out.println("Learn Java".length()); // 10
}
}
In the above program, the length of "Java\n"
string is 5 instead of 6. It is because \n
is a single character (newline) in Java.
