这是一个用java编写的关于GUI应用编程的简单的计算器的样例

package frame;

public class Model {
          double a1;
          double a2;
          
          public double getA1() {
			return a1;
		}
		public void setA1(double a1) {
			this.a1 = a1;
		}
		public double getA2() {
			return a2;
		}
		public void setA2(double a2) {
			this.a2 = a2;
		}
		public double add(){
        	  return a1+a2;
          }
          public double plus(){
        	  return a1-a2;
            }
          public double che(){
        	  return a1*a2;
            } 
          public double chu(){
        	  return a1/a2;
            }
}
