Since number1 is less than number2, the program prints the value of the a1 variable, which is set to true. Comparing the variables in Java This Java example demonstrates the use of Boolean variables and the equality operator. Here's a breakdown of the code: class demoprogram { public st...
接口是抽象类的延伸,在 Java 8 之前,它可以看成是一个完全抽象的类,也就是说它不能有任何的方法实现。 从Java 8 开始,接口也可以拥有默认的方法实现,这是因为不支持默认方法的接口的维护成本太高了。在 Java 8 之前,如果一个接口想要添加新的方法,那么要修改所有实现了该接口的类。 接口的成员(字段 + 方法...
