ex1.java

我在学习JAVA的讲义

public class Ex1{
    int x;
    public static void main(String ar[]){
        int y=0;
        Ex1 c=new Ex1();
        try{
	        y=3/c.x;
        	y=y+1;
        	System.out.println("program ends ok");
        	System.out.println(y);
        }catch (ArithmeticException e ){
        	System.out.println(e);
        }
     }
}
