The equals() method compares this string to the specified object. The result is true if and only if the argument is not null and is a String object that represents the same sequence of characters as this object.Example Live Demopublic class Sample {    public static void main(String []args) {       String s1 = "tutorialspoint";       String s2 = "tutorialspoint";       String s3 = new String ("Tutorials Point");       System.out.println(s1.equals(s2));       System.out.println(s2.equals(s3));    } }Outputtrue falseYou can also compare two strings using == operator. But, it compares references of the given ... Read More

You can compare two Strings in Java using the compareTo() method, equals() method or == operator.The compareTo() method compares two strings. The comparison is based on the Unicode value of each character in the strings. The character sequence represented by this String object is compared lexicographically to the character sequence represented by the argument string. The result is a negative integer if this String object lexicographically precedes the argument string.The result is a positive integer if this String object lexicographically follows the argument string. The result is zero if the strings are equal, compareTo returns 0 exactly when the equals(Object) method would ...

We all know that the String class in Java is mutable i.e. once we create a String variable we cannot modify its data or do any manipulations.But, there may be scenarios where we need to modify the data of String variables. In such cases, we could use StringBuffer class.This class −is like a String, but can be modified. It contains some particular sequence of characters, but the length and content of the sequence can be changed through certain method calls.Is safe for use by multiple threads.

The compareTo() method compares two strings lexicographically. The comparison is based on the Unicode value of each character in the strings. The character sequence represented by this String object is compared lexicographically to the character sequence represented by the argument string.The result is a negative integer if this String object lexicographically precedes the argument string. The result is a positive integer if this String object lexicographically follows the argument string. The result is zero if the strings are equal, compareTo returns 0 exactly when the equals(Object) method would return true.ExampleLive Demopublic class StringDemo {    public static void main(String[] args) {   ...

You can check the equality of two Strings in Java using the equals() method. This method compares this string to the specified object. The result is true if and only if the argument is not null and is a String object that represents the same sequence of characters as this object.Exampleimport java.lang.* public class StringDemo {    public static void main(String[] args) {       String str1 = "Tutorialspoint";       String str2 = "Tutorialspoint";       String str3 = "Hi";             // checking for equality       boolean retval1 = ...
