To find length of a String you can use length() method of the Java String class. This method returns the count of characters in the String object including spaces.
Java String length() method examples
1. In the examples there are two strings and length of those String is calculated using length() method.
public class StringLength {
public static void main(String[] args) {
String str1 = "String length method";
//separated by 4 spaces
String str2 = "Hello World";
System.out.println("Length of str1- " + str1.length());
System.out.println("Length of str2- " + str2.length());
}
}
Output
Length of str1- 20 Length of str2- 14
2- Printing each character by iterating a String, using String’s length() method to limit the iteration.
public class StringLength {
public static void main(String[] args) {
String str = "Hello";
for(int i = 0; i < str.length(); i++) {
System.out.println(str.charAt(i));
}
}
}
Output
