for (int i = 0; i 128; i++) {
// 【代码5】
// //将i转换为char类型，执行people.printLetter()方法，如果出现异常则捕获，并输出异常的错误信息！
people.printLetter((char) i);
}
for (int i = 0; i 128; i++) {
// 【代码6】 //将i转换为char类型，执行people. printDigit
// ()方法，如果出现异常则捕获，并输出异常的错误信息！
people.printDigit((char) i);

吞食鱼用java写的代码__
定义一个鱼的Class
给鱼一个属性 表示它的大小
当碰撞处理判断到两条鱼接触时 比较两条鱼的大小属性 然后控制程序让大的吃掉小的就是了
