JAVA 静态代码块
示例代码:
public class Test01 {
public Test01(){
System.out.println("this is constructor code"); //构造函数代码块
}
{
System.out.println("this is construction code"); //构造代码块
}
static {
System.out.println("this is static code"); //静态代码块
}
public static void main(String[] args) {
new Test01();
new Test01();
}
}
运行结果:
this is static code
this is construction code
this is constructor code
this is construction code
this is constructor code
可以看到显示static代码初始化,然后是构造方法初始化,然后是构造函数初始化,并且静态代码只会初始化一次。
