StringCharacterIterator equals() method in Java with Examples

Last Updated : 29 Jul, 2019

The equals() method of java.text.StringCharacterIterator class in Java is used to check for equality of this StringCharacterIterator with the specified StringCharacterIterator. This method takes a StringCharacterIterator instance and compares it with this StringCharacterIterator and returns a boolean value representing the same. Syntax:

public boolean equals(Object obj)

Parameter: This method accepts a parameter obj which is the StringCharacterIterator to be checked for equality with this StringCharacterIterator. Return Value: This method returns an boolean which tells if this StringCharacterIterator is equal to the specified Object. Exception: This method do not throw any Exception. Program:

Java

// Java program to demonstrate
// the above method

import java.text.*;
import java.util.*;

public class StringCharacterIteratorDemo {
    public static void main(String[] args)
    {

        StringCharacterIterator sci1
            = new StringCharacterIterator(
                "GeeksforGeeks");

        System.out.println("StringCharacterIterator 1: "
                           + sci1);

        StringCharacterIterator sci2
            = new StringCharacterIterator(
                "Geeks for Geeks");

        System.out.println("StringCharacterIterator 2: "
                           + sci2);

        StringCharacterIterator sci3
            = (StringCharacterIterator)sci1
                  .clone();

        System.out.println("StringCharacterIterator 3: "
                           + sci3);

        System.out.println("Comparing DFS 1 and DFS 2: "
                           + sci1.equals(sci2));

        System.out.println("Comparing DFS 2 and DFS 3: "
                           + sci2.equals(sci3));

        System.out.println("Comparing DFS 1 and DFS 3: "
                           + sci1.equals(sci3));
    }
}

Output:

StringCharacterIterator 1: java.text.StringCharacterIterator@bd43b778
StringCharacterIterator 2: java.text.StringCharacterIterator@ac5740a8
StringCharacterIterator 3: java.text.StringCharacterIterator@bd43b778
Comparing DFS 1 and DFS 2: false
Comparing DFS 2 and DFS 3: false
Comparing DFS 1 and DFS 3: true
