Answer 1

建议楼主采用这种方法
==================================学生类===================================

public class Student {

private String name;

private int age;

private int result;

/**
* 打印学生信息
* @param s 学生对象
*/
public void outStudentMess(Student s){
System.out.println("学生姓名：" + s.getName() + " 学生年龄:" + s.getAge() + " 学生成绩:" + s.getResult());
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public int getAge() {
return age;
}

public void setAge(int age) {
this.age = age;
}

public int getResult() {
return result;
}

public void setResult(int result) {
this.result = result;
}
}
================================教师类====================================

public class Teacher{
private String name;

private int age;

private long salary;

/**
* 老师类调用打印学生信息方法
* @param s
*/
public void outStudentsMess(Student s){
new Student().outStudentMess(s);
}

/**
* 教师给学生加分方法
* @param addResult 所加的分数
* @param s 学生对象
*/
public void addStudentsResult(int addResult, Student s){
int beforeAdd = s.getResult();
s.setResult(s.getResult() + addResult);
int afterAdd = s.getResult();
System.out.println("学生 " + s.getName() + " 分数，加分之前：" + beforeAdd + " 加分之后：" + afterAdd);
}

/**
* 教师给教师加钱方法
* @param addResult 所加的分数
* @param s 老师对象
*/
public void addTeacherSal(long addSalary, Teacher t){
long beforeAdd = t.getSalary();
t.setSalary(t.getSalary() + addSalary);
long afterAdd = t.getSalary();
System.out.println("老师 " + t.getName() + " 钱数，加钱之前：" + beforeAdd + " 加钱之后：" + afterAdd);
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public int getAge() {
return age;
}

public void setAge(int age) {
this.age = age;
}

public long getSalary() {
return salary;
}

public void setSalary(long salary) {
this.salary = salary;
}
}
=============================测试类========================================

public class Test {
public static void main(String[] args) {
Student s = new Student();
s.setAge(12);
s.setName("王二麻子");
s.setResult(55);

Student s1 = new Student();
s1.setAge(15);
s1.setName("谢臭脚");
s1.setResult(65);

Teacher t = new Teacher();
t.setAge(55);
t.setName("张大嘴");
t.setSalary(2000);

s.outStudentMess(s1);
s.outStudentMess(s);

t.outStudentsMess(s1);
t.addStudentsResult(5, s1);
t.addStudentsResult(16, s);

t.addTeacherSal(510, t);
}
}

这些题很面熟 好像是出自同一人之手吧 既然去学了就自己完成 别人告诉你答案有什么用
要是那样的话 还不如不去学呢

Answer 3

public class Teacher{
private String name;
private int salary,age;
Student s=null;
publicTeacher(int salary){
this.salary=salary;
}
public int getSalary(){
return salary;
}
public void setSalary(int salary){
this.salary+=salary;
}
public String getString(){
return s.getString();
}
public void setStudentChengJi(int chengji){
s.setChengJi(chengji);
}
public static void main(String[] args){
s=new Student("小马",12,63);
Teacher t=new Teacher(2000);
System.out.println(t.getString());
System.out.println("加分前");
System.out.println(s.getChengJi());
t.setStudentChengJi(5);
System.out.println("加分后");
System.out.println(s.getChengJi());
System.out.println("加工资前");
System.out.prinltn(s.getSalary());
t.setSalary(500);
System.out.println("加工资后");
System.out.prinltn(s.getSalary());
}
}
class Student{
private String name;
private int age;
private int chengji;
public Student(String name,int age,int chengji){
this.name=name;
this.age=age;
this.chengji=chengji;
}
public void setChengJi(int chengji){
this.chengji+=chengji;
}
public int getChengJi(){
return chengji;
}
public String getString(){
return name+"今年"+age+"分数是"+chengji;
}
}
