static相关
1.代码块
public class StaticDemo {
{
System.out.println("匿名代码块");
}
static{
System.out.println("静态代码块");
}
public StaticDemo(){
System.out.println("构造函数");
}
public static void main(String[] args) {
StaticDemo demo=new StaticDemo();
System.out.println("==================");
StaticDemo demo1=new StaticDemo();
}
}
执行结果：
2.静态导入包
import static java.lang.Math.random;
public class Demo02 {
public static void main(String[] args) {
System.out.println(random());
}
}
