java考试编程题
public class Circle {
private double radius;//Circle类的成员变量：radius 半径
// Circle类的方法成员：Circle( ) 构造方法，将半径置为1；
public Circle() {
radius=1;
}
// Circle(double r) 构造方法，创建Circle对象时将半径初始化为r；
public Circle(double r) {
radius = r;
}
// double getRadius() 获得圆的半径值
public double getRadius(){
return radius;
}
// double getPerimeter() 获得圆的周长
double getPerimeter(){
return 2*Math.PI*getRadius();
}
// double getArea() 获得圆的面积
public double getArea(){
return Math.PI*getRadius()*getRadius();
}
// void circlePrint() 将圆的半径，周长，面积输出到屏幕
public void circlePrint(){
System.out.println("radius="+getRadius());
System.out.println("Perimeter="+getPerimeter());
System.out.println("Area="+getArea());
}
public static void main(String args[]) {
new Circle().circlePrint();//调用默认的构造函数，如果要对半径赋值，在括号里赋值即可
}
}
‘贰’ JAVA 考试编程题如何编写一个矩形类
用这个肯定可以
public class Rectangle {
private float width;//长
private float height;//宽
public Rectangle(float width, float height){
this.width = width;
this.height = height;
}
//计算周长= （长+宽）＊2
public float calcCircle(){
return (width + height) * 2;
}
//计算面积 长＊宽
public float calcArea(){
return width * height;
}
public float getHeight() {
return height;
}
public void setHeight(float height) {
this.height = height;
}
public float getWidth() {
return width;
}
public void setWidth(float width) {
this.width = width;
}
}
‘叁’ java考试，求编程题步骤！！！
public class Test1 {
public static void main(String[] args) {
int sum=0;
for (int i = 1; i <=50; i++) {
if(i%2==1){
sum+=i;
}
}
System.out.println("1到50之内奇数和为："+sum);
}
}
另外一种用while的方法：
public class Test1 {
public static void main(String[] args) {
int sum=0;
int i=1;
while(i<=50){
if(i%2==1){
sum+=i;
}
i++;
}
System.out.println("1到50之内奇数和为："+sum);
}
}
‘肆’ java面向对象程序设计期末考试编程题！急！！！
===============================第一题==============================
import java.applet.Applet;
import java.awt.Color;
import java.awt.Label;
public class test extends Applet {
private Label label;
@Override
public void init() {
label=new Label("欢迎来到java世界！");
label.setBackground(Color.BLUE);
setBackground(Color.PINK);
add(label);
}
}
===============================第二题==============================
因为没图,所以自己设计的界面..
import java.awt.BorderLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;

label=new JLabel("显示内容");
jt=new JTextArea(10,20);
jsp=new JScrollPane(jt);
show = new JButton("显示给定内容");
JPanel panel=new JPanel();
panel.add(label);
panel.add(show);
frame.add(jsp,BorderLayout.NORTH);
frame.add(panel,BorderLayout.SOUTH);
