Java 中的布尔等于()方法，示例
原文:https://www . geesforgeks . org/boolean-equals-method-in-Java-with-examples/
布尔类的 equals() 方法是 Java 的一个内置方法，用于检查两个布尔对象的相等性。
语法:
BooleanObject.equals(Object ob)
参数:它以对象类型的参数 ob 作为输入，这是要比较的实例。
返回类型:返回类型为布尔。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:
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));
}
}
Output:
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));
}
}
Output:
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));
}
}
Output:
false comparing with true = false
