Java StringWriter equals()用法及代码示例

Java中StringWriter类的Java.io.StringWriter.equals(Object obj)方法用于检查StringWriter的两个实例是否相等。它返回一个布尔值，说明它们是否相等。

签名：

public boolean equals(StringWriter second_StringWriter)

用法:

first_StringWriter.equals(second_StringWriter)

参数：此方法接受强制性参数second_StringWriter，该参数表示要与第一个StringWriter进行比较的第二个StringWriter。

返回值：如果相等相等且对象和StringWriter相等，则该方法返回true，否则返回false。

下面的程序用于说明java.io.StringWriter.elements()方法的用法：

示例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)); 
    } 
}

输出：

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

示例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)); 
    } 
}

输出：

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