Java中的main方法调用非静态方法处理

public class Object {
    public static void main(String[] args) {
        System.out.println(Object.totring());
    }
    public String totring() {
        return ("在" + Object.class.getName() + "类中写totring()方法");
    }
}

public class Object {
    public static void main(String[] args) {
        Object xiaoming = new Object(); // 类实例化为对象
        System.out.println(xiaoming.totring()); //打印输出,也可匿名化实例对象,直接是 ==> new Object().toString()
    }
    public String totring() {
        return ("在" + getClass().getName() + "类中写totring()方法");
    }
}

public class Object {
    public static void main(String[] args) {
        System.out.println(Object.totring());
    }
    public static String totring() {
        return ("在" + Object.class.getName() + "类中写totring()方法");
    }
}

public class text1{
public static void main(String [] args){
int a = 12;
int b = 23;
text1 aa = new text1();
aa.add(a,b);
}
public void add(int a,int b){
System.out.println("计算的结果是："+(a+b));
}
}
