public class Sample {

    public void method()
    {
        System.out.println("normal hai");   
    }
    public static void method1()
    {
        System.out.println("static hai");
    }
    public static void main(String[] args) {
        Sample s = null;
        s.method1();
        s.method(); 
    }
}

输出是:

Exception in thread "main" java.lang.NullPointerException
        at com.csvfile.sample.main(Sample.java:22)

static hai

为什么订单改变了？它应该输出:

static hai
Exception in thread "main" java.lang.NullPointerException
    at com.csvfile.sample1.main(Sample.java:22)
