Use of length() method to find size of String Java public class Geeks { public static void main(String[] args){ // Here str is a string object String str = "GeeksforGeeks"; System.out.println(str.length()); } } OutputThe size of the String is 13 2. Compare the size of two Strings Java // whether the length of two strings is // equal or not using the length() method import java.io.*; class Geeks { public static void main(String[] args) { String s1 = "abc"; String s2 = "xyz"; // storing the length of both the // strings in int variables int len1 = s1.length(); int len2 = s2.length(); // checking whether the length of // the strings is equal or not if (len1 == len2) { System.out.println("The length of both the strings"+ " are equal and is "+ len1); } else { System.out.println("The length of both the strings"+ " are not equal"); } } } OutputThe length of both the strings are equal and is 3 Comment More infoAdvertise with us Next Article Java String length() Method C code_r Follow Improve Article Tags : Java Java-String-Programs Practice Tags : Java Similar Reads StringJoiner length() method in Java The length() of StringJoiner is used to find out the length of the StringJoiner in characters.
