When a class extends a class, then it is called single inheritance. If a class extends more than one class, it is called multiple inheritance, which is not allowed in Java. However, you can achieve similar resu

正常的方法调用需要像上面提到的那样:object.method(parameters),但由于身处同一个类中,this.printAdlerOneQuote();就可以简写成:printAdlerOneQuote();。 完整的程序代码如下: public class HelloWorld { public static void main(String[] args) { System.out.println("Hello World!"); printAdlerOneQuote(); ...

The Main class extends the Data class. This program first stores an instance of the j.u.HashMap class wrapped in the j.u.Collections.synchronizedMap() method into a sharedMap 36 variable, and stores one instance into a sharedInt variable. Though the HashMap class is not thread-safe, the...
