Java.io. _ El método StringWriter .equals(Object obj) de la clase StringWriter en Java se utiliza para verificar si las dos instancias de StringWriter son iguales o no. Devuelve un valor booleano que indica si son iguales o no.
Firma:
public boolean equals(StringWriter second_StringWriter)
Sintaxis:
first_StringWriter.equals(second_StringWriter)
Parámetros: este método acepta un parámetro obligatorio second_StringWriter que hace referencia al segundo StringWriter para compararlo con el primer StringWriter.
Valor devuelto: el método devuelve verdadero si se mantiene la igualdad y tanto los objetos como StringWriter son iguales; de lo contrario, devuelve falso .
Los siguientes programas se utilizan para ilustrar el funcionamiento del método java.io.StringWriter.elements():
Programa 1:
// Java code to illustrate the equals() method
import java.io.*;
public class StringWriter_Demo {
public static void main(String[] args)
{
// Creating an empty StringWriter
StringWriter writer1 = new StringWriter();
// Inserting elements into the StringWriter
writer1.write("GeeksForGeeks");
// Displaying the StringWriter
System.out.println("StringWriter 1: "
+ writer1.toString());
// Creating an empty StringWriter
StringWriter writer2 = new StringWriter();
// Inserting elements into the StringWriter
writer2.write("GFG");
// Displaying the StringWriter
System.out.println("StringWriter 2: "
+ writer2.toString());
System.out.println("Are both of them equal? "
+ writer1.equals(writer2));
}
}
StringWriter 1: GeeksForGeeks StringWriter 2: GFG Are both of them equal? false
Programa 2:
// Java code to illustrate the equals() method
import java.io.*;
public class StringWriter_Demo {
public static void main(String[] args)
{
// Creating an empty StringWriter
StringWriter writer1 = new StringWriter();
// Inserting elements into the StringWriter
writer1.write("GFG");
// Displaying the StringWriter
System.out.println("StringWriter 1: "
+ writer1.toString());
// Creating an empty StringWriter
StringWriter writer2 = new StringWriter();
// Inserting elements into the StringWriter
writer2.write("GFG");
// Displaying the StringWriter
System.out.println("StringWriter 2: "
+ writer2.toString());
System.out.println("Are both of them equal? "
+ writer1.equals(writer2));
}
}
StringWriter 1: GFG StringWriter 2: GFG Are both of them equal? false
