Java 构造器（构造方法）练习

 

 

package com.bytezero.triangle;

public class TriAngle 
{
    //私有属性
    private double base; //边长
    private double height;  //高
    
    //构造器
    public TriAngle()
    {
        
    }
    
    public TriAngle(double b,double h)
    {
        base = b;
        height = h;
    }
    
    //方法
    public void setBase(double b)
    {
        base = b;
    }
    
    public double getBase()
    {
        return base;
    }
    
    public void setHeight(double h)
    {
        height = h;
    }
    public double getHeight()
    {
        return height;
    }
    
    
    
}

package com.bytezero.triangle;

public class TriAngleTest 
{
    public static void main(String[] args)
    {
        TriAngle t1 = new TriAngle();
        t1.setBase(2.2);
        t1.setHeight(3.3);
        System.out.println("base :"+t1.getBase()+",  height："+t1.getHeight());
