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 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
