Java继承实现接口的抽象类

1、TestIntace.java

package com.chase.abstrac;

/**
 * 接口
 * @author Chase
 *
 * @date 2013-10-21 下午02:29:12
 *
 * @version V1.0
 */
public interface TestIntface {

    void test1();//方法1

    void test2();//方法2

    void test3();//方法3
}

2、TestAbstract.java

package com.chase.abstrac;

/**
 * 实现TestIntface接口的 抽象类
 * @author Chase
 *
 * @date 2013-10-21 下午02:29:57
 *
 * @version V1.0
 */
public abstract class TestAbstract implements TestIntface {

    public void test1(){System.err.println("我是test1");};

    public void test2(){};

    public void test3(){System.err.println("我是test3");}
}

3、TestExtendsAbstract.java

package com.chase.abstrac;

/**
 * 继承 实现TestIntface接口的 抽象类 的 子类
 * @author Chase
 *
 * @date 2013-10-21 下午02:31:04
 *
 * @version V1.0
 */
public class TestExtendsAbstract extends TestAbstract {

    public void test3() {
        System.out.println("test3()");
    }

}

4、TestMain.java

package com.chase.abstrac;

/**
 * 程序入口类
 * @author Chase
 *
 * @date 2013-10-21 下午02:32:14
 *
 * @version V1.0
 */
public class TestMain {

    static TestIntface intface = new TestExtendsAbstract();

    public static void main(String[] args) {
        intface.test3();
        intface.test1();

    }
}
