1.面向对象编程

package 面向;

import org.omg.Messaging.SyncScopeHelper;

public class 三角形 {
    
         //属性
    
    String nj;
    
    String bbb;   int d;    int j;//分别是角、边、点、角
    
    //方法 
    
    void dengbiansanjiaoxing(int d1)
    {
        j+=d1;
        System.out.printf("三角形有"+d1,"三角形有"+d1);
    }
    
}



package 面向;

public class TESTsanjiaoxing {

    public static <SanJiaoXing> void main(String[] args) {
    
        int d;
        
        sanjiaoxing dian=new sanjiaoxing();
        
     dian.d="3";
        
       System.out.printf("三角形有"+ dian.d+"条边");
    }

}
