Class Test{

Public static void main(String[] args){

Inta=3;

Intb=6;

System.out.println(a= =b);

System.out.println(a<=b);

System.out.println(a!=b);
System.out.println(a>=b);
}
}
上述程序运行结束时,输出结果是（）

Class Test{

Private static String name;

Static{

Name="World";

System.out.print(name);}

Public static void main(String[] args){

System.out.print("Hello");

Test test = new Test();}

}

程序运行结果是（）

Class Person{

Void say(){

System.out.println("hello");

Class Example{

Public static void main(String[]args){

Person p2=new Person();

Person pl=new Person();

P2.say();

P1.say();

P2=null;

P2.say();}}

下列选项中描述正确的是（）

Public class A {

Public static void main(String[] args) {

Bb =new B();

b.test();

void test() {

System.out.print("A");

}

}class B extends A {

Void test() {

Super.test();

System.out.print("B");

}

}

Class Dog {

Public String name;

Dog(String name){

This .name =name;

}

}

Public class Demo1{

Public static void main(string[]args){

Dog dog1=new Dog("xiaohuang");

Dog dog2= new Dog("xiaohuang");

String s1=dog1.toString();

String s2=dog2.toString();

String s3="xiaohuang";

String s4="xiaohuang";

}

}

返回值为 true 的是（）
