JAVA程序编写一个学生类Student
Public Class Student{
Public long id;
Public String name;
Public int age;
Public boolean sex;
Public long phone;
Public Student(long i,String n,int a,boolean s,long p){
this.id = i;
this.name = n;
this.age = a;
this.sex = s;
this.phone = p;
}
Public int getage(){
return this.age;
}
Public long getphone(){
return this.phone;
}
Public String toString(){
return this.name;
}
Public static void main(String[]args){
Student student = new Student(01,"李明",20,true,13xxx);
System.out.println(student.age());
System.out.println(student.getphone());
System.out.println(student.toString());
}
}
java定义一个学生类Student

package wo;
-
public class StudentText{
public static void main(String[] args) {
Student s1=new Student(01,"张三");
Student s2=new Student(02,"李四");
boolean b=s1.equals(s2);
System.out.println(b);
}
}
class Student {
private int num;
private String nema;
public Student(int num, String nema) {
super();
this.num = num;
this.nema = nema;
}
public Student() {
}
public int getNum() {
return num;
}
public void setNum(int num) {
this.num = num;
}
public String getNema() {
return nema;
}
public void setNema(String nema) {

return true;
if (obj == null)
return false;
if (getClass() != obj.getClass())
return false;

java设计一个Student类
public class Student{
private String sName;
private String sClass;
private String sID;
Student(String sID,String sName)
{
this.sID = sID;
this.sName = sName;
}

{
this(sID,sName);
this.sClass = sClass;
}
public String toString()
{
String ret = "";
if(sName != null)
{
ret = ret + sName;
}
if(sID != null)
{
ret = ret + "(" + sID + ",";
}else
{
ret =ret + "( ,";
}
if(sClass != null)
{
ret = ret + sClass + ")";
}else
{
ret = ret + " )";
}
return ret;
}
public String getsName() {
return sName;
}
public void setsName(String sName) {
this.sName = sName;
}
public String getsClass() {
return sClass;
}
public void setsClass(String sClass) {
this.sClass = sClass;
}
public String getsID() {
return sID;
}
public void setsID(String sID) {
this.sID = sID;
}
}
public class StudentDemo{
public static void main(String[] args)
{
Student[] st = new Student[5];
st[0] = new Student("student0","id0","class0");

for(int i = 0 ; i st.length; i++)
{
System.out.println(st[i].toString());
}
}
}
