IT技术word2Vec

用java编写一个简单例子，题目如下package test;
public class Student {
private String name;
private String id;
private String clazz;
private int age;
private String address;
/**
* sayHello方法
*/
public void sayHello() {
System.out.println("学号为" + this.id + "的同学的具体信息如下：");
System.out.println("姓名：" + this.name);
System.out.println("班级：" + this.clazz);
System.out.println("年龄：" + this.age);
System.out.println("家庭住址：" + this.address);
}
/**
* 测试方法
*
* @param args
*/
public static void main(String[] args) {
// 第一问
Student student = new Student();
student.setAddress("百度知道");
student.setAge(1);
student.setClazz("一班");
student.setId("071251000");
student.setName("lsy605604013");
student.sayHello();
// 第二问
Student studentNew = new Student();
studentNew.setAddress("搜搜知道");
studentNew.setAge(2);
studentNew.setClazz("二班");
studentNew.setId("071251001");
studentNew.setName("lady");
if (student.getAge()studentNew.getAge())
studentNew.sayHello();
else if (student.getAge()studentNew.getAge())
student.sayHello();
else
System.out.println("两人一样大");
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getClazz() {
return clazz;
}
public void setClazz(String clazz) {
this.clazz = clazz;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
}
求一个简单的java代码public class Message {
public static void main(String[] args){
String name;
int age;
System.out.println("请输入姓名，回车结束："); //提示输入
Scanner sc = new Scanner(System.in);
name = sc.nextLine();//为变量赋值
System.out.println("请输入年龄，回车结束：");
age = sc.nextInt();
System.out.println("姓名："+name+"\n年龄："+age); //打印姓名及年龄
}
}
//不知道这样行么？
java代码示例importjava.awt.*;importjava.awt.event.*;classShopFrameextendsFrameimplementsActionListener{Labellabel1,label2,label3,label4;Buttonbutton1,button2,button3,button4,button5;TextAreatext;Panelpanel1,panel2;staticfloatsum=0.0f;ShopFrame(Strings){super(s);setLayout(newBorderLayout());label1=newLabel("面纸：3元",Label.LEFT);label2=newLabel("钢笔：5元",Label.LEFT);label3=newLabel("书：10元",Label.LEFT);label4=newLabel("袜子：8元",Label.LEFT);button1=newButton("加入购物车");button2=newButton("加入购物车");button3=newButton("加入购物车");button4=newButton("加入购物车");button5=newButton("查看购物车");text=newTextArea("商品有："+"\n",5,10);text.setEditable(false);addWindowListener(newWindowAdapter(){publicvoidwindowClosing(WindowEvente){System.exit(0);}});button1.addActionListener(this);button2.addActionListener(this);button3.addActionListener(this);button4.addActionListener(this);button5.addActionListener(this);panel1=newPanel();panel2=newPanel();panel1.add(label1);panel1.add(button1);panel1.add(label2);panel1.add(button2);panel1.add(label3);panel1.add(button3);panel1.add(label4);panel1.add(button4);panel2.setLayout(newBorderLayout());panel2.add(button5,BorderLayout.NORTH);panel2.add(text,BorderLayout.SOUTH);this.add(panel1,BorderLayout.CENTER);this.add(panel2,BorderLayout.SOUTH);setBounds(100,100,350,250);setVisible(true);validate();}publicvoidactionPerformed(ActionEvente){if(e.getSource()==button1){text.append("一个面纸、");sum=sum+3;}elseif(e.getSource()==button2){text.append("一只钢笔、");sum=sum+5;}elseif(e.getSource()==button3){text.append("一本书、");sum=sum+10;}elseif(e.getSource()==button4){text.append("一双袜子、");sum=sum+8;}elseif(e.getSource()==button5){text.append("\n"+"总价为："+"\n"+sum);}}}publicclassShopping{publicstaticvoidmain(String[]args){newShopFrame("购物车");}}java项目代码例子我没用Swing可能显示不出来你的效果 。不满意得话java项目代码例子我在给你编一个 。
