類初始化實例分析

測試前先準(zhǔn)備兩個繼承關(guān)系的類
父類：

/**
 * @author 公眾號：IT三明治
 * @date 2021/7/5
 */
public class SuperClazz {

    static {
        System.out.println("SuperClazz init! ");
    }

    public static int value = 111;
    public static final  String SANDWICH  = "Sandwich";
    public static final int WHAT = value;
}

子類：

/**
 * @author 公眾號：IT三明治
 * @date 2021/7/5
 */
public class SubClazz extends SuperClazz{

    static {
        System.out.println("SubClazz init! ");
    }
}

1.new一個類翩肌，并觀看他的類加載情況

/**
 * @author 公眾號：IT三明治
 * -XX:+TraceClassLoading 通過vm參數(shù)觀察類加載
 * @date 2021/7/5
 */
public class Initialization {
    public static void main(String[] args) {
        Initialization initialization = new Initialization();
        initialization.method1(); //new 一個父class
    }

    public void method1() {
        //new super class 就會初始化父class
        SuperClazz superClazz = new SuperClazz();
    }
}

由此可見痰驱，如此簡單的一個main實例饭玲，其實我們需要加載了這么多jre的基礎(chǔ)類庫
字節(jié)碼出現(xiàn)new砚婆，就會初始化類本身：

類加載和初始化結(jié)果：
類加載和初始化結(jié)果

2.new一個子class

/**
 * @author 公眾號：IT三明治
 * -XX:+TraceClassLoading 通過vm參數(shù)觀察類加載
 * @date 2021/7/5
 */
public class Initialization {
    public static void main(String[] args) {
        Initialization initialization = new Initialization();
        initialization.method2(); //new 一個子class
    }
    public void method2() {
        //new sub class 會連父class一起初始化
        SubClazz subClazz = new SubClazz();
    }
}

輸出結(jié)果



由此可見new子class拓哺，父class也會初始化

3. 打印子類的靜態(tài)字段

/**
 * @author 公眾號：IT三明治
 * -XX:+TraceClassLoading 通過vm參數(shù)觀察類加載
 * @date 2021/7/5
 */
public class Initialization {
    public static void main(String[] args) {
        Initialization initialization = new Initialization();
        initialization.method3(); //打印子類的靜態(tài)字段
    }

    public void method3() {
        System.out.println(SubClazz.value);
    }
}

從輸出結(jié)果看出：通過子類引用父類中的靜態(tài)字段比伏，只會觸發(fā)父類初始化弥锄，而不會觸發(fā)子類的初始化（但是子類會被加載）


從字節(jié)碼分析沼侣，有g(shù)etstatic字節(jié)碼的時候都會初始化相關(guān)類

4.使用數(shù)組方式創(chuàng)建對象

/**
 * @author 公眾號：IT三明治
 * -XX:+TraceClassLoading 通過vm參數(shù)觀察類加載
 * @date 2021/7/5
 */
public class Initialization {
    public static void main(String[] args) {
        Initialization initialization = new Initialization();
        initialization.method4(); //使用數(shù)組方式創(chuàng)建對象
    }
    public void  method4() {
        SuperClazz[] sca = new SuperClazz[10];
    }
}

使用數(shù)組的方式祖能，不會觸發(fā)初始化（同樣不會觸發(fā)子類加載）。
由下圖可見蛾洛，在Initialization類加載后直至退出程序都沒有看到SuperClazz類和它的子類被加載养铸，更沒有被初始化。

5.打印一個常量

public class Initialization {
    public static void main(String[] args) {
        Initialization initialization = new Initialization();
        initialization.method5(); //打印一個常量
    }
    public void method5() {
        System.out.println(SuperClazz.SANDWICH);
    }

打印一個常量轧膘，不會觸發(fā)初始化（同樣不會觸發(fā)類加載）钞螟。
由下圖可見，Initialization類被加載后谎碍，直至程序退出并沒有加載SuperClazz類和它的子類鳞滨，更不會初始化它們，但是常量正常打印了蟆淀。


6.使用常量去引用另外一個常量

/**
 * @author 公眾號：IT三明治
 * -XX:+TraceClassLoading 通過vm參數(shù)觀察類加載
 * @date 2021/7/5
 */
public class Initialization {
    public static void main(String[] args) {
        Initialization initialization = new Initialization();
        initialization.method6(); //使用常量去引用另外一個常量
    }
    public void method6() {
        System.out.println(SuperClazz.WHAT);
    }
}

如果使用常量去引用另外一個常量（這個值未知拯啦，所以需要觸發(fā)初始化）。
由下圖可知類加載并初始化完成熔任。


由字節(jié)碼分析可見這里需要觸發(fā)getstatic字節(jié)碼褒链，所以需要初始化。
