Java BooleanObject equals()方法及示例

布尔类的 equals() 方法是Java中的一个内置方法，用于检查两个布尔对象的平等性。

语法

BooleanObject.equals(Object ob)

参数： 它接受一个Object类型的参数ob作为输入，它是要比较的实例。

返回类型： 返回类型是 布尔型 如果指定的对象’ob’与’BooleanObject’的值相同，则返回真，否则返回假。

下面的程序说明了布尔类的equals()方法。

程序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

程序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

程序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
