Java Boolean equals()用法及代码示例

布尔类的equals()方法是Java的一种内置方法，用于检查两个布尔对象的相等性。

用法:

BooleanObject.equals(Object ob)

参数：它采用对象类型的参数ob作为输入，这是要比较的实例。

返回类型：返回类型为布尔值。如果指定的对象“ ob”与“ BooleanObject”具有相同的值，则返回true，否则返回false。

下面是说明布尔类的equals()方法的程序：

示例1:

// Java code to implement 
// equals() method of Boolean class 
  
class GeeksforGeeks { 
  
    // Driver method 
    public static void main(String[] args) 
    { 
  
        // Boolean object 
        Boolean a = new Boolean(true); 
  
        // Boolean object 
        Boolean b = new Boolean(true); 
  
        // compare method 
        System.out.println(a + " comparing with " + b 
                           + " = " + a.equals(b)); 
    } 
}

输出：

true comparing with true = true

示例2:

// Java code to implement 
// equals() method of Java class 
  
class GeeksforGeeks { 
  
    // Driver method 
    public static void main(String[] args) 
    { 
  
        // Boolean object 
        Boolean a = new Boolean(true); 
  
        // Boolean object 
        Boolean b = new Boolean(false); 
  
        // compare method 
        System.out.println(a + " comparing with " + b 
                           + " = " + a.equals(b)); 
    } 
}

输出：

true comparing with false = false

示例3:

// Java code to implement 
// equals() method of Java class 
  
class GeeksforGeeks { 
  
    // Driver method 
    public static void main(String[] args) 
    { 
  
        // Boolean object 
        Boolean a = new Boolean(false); 
  
        // Boolean object 
        Boolean b = new Boolean(true); 
  
        // compare method 
        System.out.println(a + " comparing with " + b 
                           + " = " + a.equals(b)); 
    } 
}

输出：

false comparing with true = false
