JAVA编程思想源代码 值得一下 很难找的

package chapter7;

abstract class abstracSuperClass {
	abstract public void Method_1();

	protected void Method_2() {
		System.out.println("SuperClass.Method_2()");
	}
}

public class AbstractClass_1 extends abstracSuperClass {

	public void Method_1() {
		System.out.println("ChildClass.Method_1()");
	}

	public static void main(String args[]) {
		AbstractClass_1 c = new AbstractClass_1();
		c.Method_1();
		c.Method_2();
