我们将某些特定的逻辑处理编写为一个方法。其某些实现的操作由子类来实现
父类定义为抽象类 其中2个为抽象方法，意为由子类来实现
父类
public abstract class TemplateDesgin {
public abstract void doAnything();
public abstract void doSomething();
public final void doTemplate(){
doAnything();
doSomething();
}
}
子类
public class Test extends TemplateDesgin {
@Override
public void doAnything() {
System.out.println("doAnything...");
}
@Override
public void doSomething() {
System.out.println("doSomething...");
}
public static void main(String[] args) {
Test test = new Test();
test.doTemplate();
}
}
例如编写程序的计数耗时
父类
public abstract class TimeCounter { public abstract void programe(); public final long timeCounterMethod(){ long startTime = System.currentTimeMillis(); programe(); long endTime = System.currentTimeMillis(); return (endTime-startTime); } }
public class Time extends TimeCounter{ @Override public void programe() { for(int i=0;i<10000000;i++){ //System.out.print(i); } } public static void main(String[] args) { Time time = new Time(); System.out.println(time.timeCounterMethod()); } }
