an interface or a convention needs to be defined, and then different scenarios can be implemented. The caller does not need to pay too much attention to specific implementation details when using it. In Java, SPI

System.out.println(“This is implemented method of Abc interface”); } } An interface can extends any number of interfaces. A demonstration is given below. interface A { // … } interface B extends A { II … } interface C { // … } interface D extends B, C { // … } interface...

public static void methodTwo(int out) { System.out.println(out); } } In the above, methodOne() called methodTwo() and passed "x" to it. methodTwo() "received" the value as "out". This is a convenient way to quickly pass a value to another method without making the value global...
