+length(): return type int

-
You can get length of a string by invoking its length() method.

import java.lang.String;
class length{
                    public static void main(String[] arg){ 
                          String str="Welcome to Java";
                          System.out.println("Length: "+str.length());
                         }
                     }

Output:  Length: 15
   
Note that length is a method in the String class but is a property in an array object. Do you have to use str.length() to get the number of characters in string str and a.length to get the number of elements in array a.

String Comparisons

The String class provides the methods for comparing strings, as given below:-                       Method                                                            Defination str2.equals(s1: String): boolean                        Returns true if this string is equal to string s1. str2.equalsIgnoreCase(s1: String): boolean      Returns true if this string is equal to string s1 case                                                                                   insensitive. str2.compareTo(s1: String): int                        Returns an integer greater than 0, equal to 0, or less                                                                                 than 0 to indicate whether this string is greater than,                                                                                 equal to, or less than s1. str2.compareToIgnoreCase(s1: String): int      Same as compareTo except that the comparison is case
