Java编写一个矩形类,并计算面积和周长?
class Rectangle{
private int width = 2;
private int length = 1;
public int getWidth(){
return this.width;
}
public void setWidth(int w){
this.width = w;
}
public int getLength(){
return this.length;
}
public void setLength(int l){
this.length = l;
}
public int getArea(){
return this.length * this.width;
}
public int getCircumference(){
return (this.length + this.width) * 2;
}
public Rectangle(){}
public Rectangle(int l, int w){
this.length = l;
this.width = w;
}
}
public class demo{
public static void main(String[] args) {
Rectangle rect = new Rectangle(30, 8);
System.out.print("长方形的面积是:");
System.out.println(rect.getArea());
System.out.printf("长方形的周长是:%d\n", rect.getCircumference());
}
}
Java编写一个矩形类,至少包含以下方法:
import java.awt.Point;
public class Rectangle {
private int widthT = 0;
private int heightT = 0;
Point point = new Point();
public Rectangle(int width, int height, int centerX, int centerY) {
widthT = width;
heightT = height;
point.x = centerX;
point.y = centerY;
}
public int width() {
return widthT;
}
public int height() {
return heightT;
}
public int centerX() {
return point.x;
}
public int centerY() {
return point.y;
}
}
麻烦采纳呦~~~亲
编写一个JAVA程序,描写一个矩形类,并输出某个矩形的长,宽,面积。具体描述如下?
// 矩形
public class RectangleDemo {
public static void main(String[] args) {
RectangleDemo demo = new RectangleDemo(12, 32);
System.out.println(demo.getPerimeter());
System.out.println(demo.getArea());
demo = new RectangleDemo();
System.out.println(demo.getArea());
System.out.println(demo.getPerimeter());
demo.setHeight(50);
demo.setWidth(30);
System.out.println(demo.getArea());
System.out.println(demo.getPerimeter());
}
// 求周
public double getPerimeter() {
return (height + width) * 2;
}
// 求面积
public double getArea() {
return height * width;
}
public RectangleDemo(double height, double width) {
this.height = height;
this.width = width;
}
public RectangleDemo() {
this.height = 10;
this.width = 10;
}
private double height;// 高度
private double width;// 宽度
public double getHeight() {
return height;
}
public void setHeight(double height) {
this.height = height;
}
public double getWidth() {
return width;
}
public void setWidth(double width) {
this.width = width;
}
}
编写矩形类RectangleJava程序矩形类两数据员别rLength宽rWidth通getLength()、getWidth()、getArea()别查看矩形、宽面积通setLength()setWidth()重新设置矩形宽
java 编写一个矩形类 rect 要求如下:
public class Rect{
private int length;
private int width;
private int startX;
private int startY
public Rect(){}
public Rect(int length,int width){
this.length = length;
this.width = width;
}
public Rect(int length,int width,int startX,int startY){
this.length = length;
this.width = width;
this.startX = startX;
this.startY = startY;
}
//不知道你要什么成员方法,我随便点....
public void louzhuhao(){
System.out.println("楼主好....");
}
public int getLength() {
return length;
}
public void setLength(int length) {
this.length = length;
}
public int getWidth() {
return width;
}
public void setWidth(int width) {
this.width = width;
}
public int getStartX() {
return startX;
}
public void setStartX(int startX) {
this.startX = startX;
}
public int getStartY() {
return startY;
}
public void setStartY(int startY) {
this.startY = startY;
}
}
