The Java.io.StringWriter.equals(Object obj) method of StringWriter class in Java is used to check whether the two instances of StringWriter are equal or not. It returns a boolean stating whether they are equal or not.
Signature:
public boolean equals(StringWriter second_StringWriter)
Syntax:
first_StringWriter.equals(second_StringWriter)
Parameters: This method accepts a mandatory parameter second_StringWriter which refers to the second StringWriter to be compared to the first StringWriter.
Return value: The method returns true if the equality holds and both the objects and StringWriter are equal else it returns false.
Below programs are used to illustrate the working of the java.io.StringWriter.elements() method:
Program 1:
import java.io.*;
public class StringWriter_Demo {
public static void main(String[] args)
{
StringWriter writer1 = new StringWriter();
writer1.write( "GeeksForGeeks" );
System.out.println( "StringWriter 1: "
+ writer1.toString());
StringWriter writer2 = new StringWriter();
writer2.write( "GFG" );
System.out.println( "StringWriter 2: "
+ writer2.toString());
System.out.println( "Are both of them equal? "
+ writer1.equals(writer2));
}
}
|
Output:
StringWriter 1: GeeksForGeeks
StringWriter 2: GFG
Are both of them equal? false
Program 2:
import java.io.*;
public class StringWriter_Demo {
public static void main(String[] args)
{
StringWriter writer1 = new StringWriter();
writer1.write( "GFG" );
System.out.println( "StringWriter 1: "
+ writer1.toString());
StringWriter writer2 = new StringWriter();
writer2.write( "GFG" );
System.out.println( "StringWriter 2: "
+ writer2.toString());
System.out.println( "Are both of them equal? "
+ writer1.equals(writer2));
}
}

Output:
StringWriter 1: GFG
StringWriter 2: GFG
Are both of them equal? false
