看下吧,有什么不足的请指出来
Java编程，填写下面的代码
class NoLowerLetterException extends Exception {
public NoLowerLetterException(String msg) {
super(msg);
}
}
class NoDigitException extends Exception {
public NoDigitException(String msg) {
super(msg);
}
}
class People {
void printLetter(char c) {
if (c = 'a' c = 'z') {
System.out.println(c);
} else {
try {
throw new NoLowerLetterException(String.valueOf(c));
} catch (NoLowerLetterException e) {
e.printStackTrace();
}
}
}
void printDigit(char c) {
if (c = '0' c = '9') {
System.out.println(c);
} else {
try {
throw new NoDigitException(String.valueOf(c));
} catch (NoDigitException e) {
e.printStackTrace();
}
}
}
}
public class ExceptionExample {
public static void main(String args[]) {
People people = new People();
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);
}
}
}
我想看一点简单的Java程序的源代码
兄弟可以联系 hi留言也行
我这里保留了，从学习java第一天起到现在 学习练习代码，
基础部分注释很详细。
//每一位相加求和

Java实验，代码怎么写？
Shape.java接口代码
public interface Shape {
public static final double PI = 3.14d;
public double area();
}
Circle.java圆类代码
public class Circle implements Shape {
private double radius;
public Circle(double radius) {
this.radius = radius;
}
@Override
public double area() {
return PI * this.radius * this.radius;
}
public double perimeter() {
return 2 * PI * this.radius;
}
}
Cylinder.java圆柱体类代码
public class Cylinder extends Circle {
private double height;
public Cylinder(double radius, double height) {
super(radius);
this.height = height;
}
public double area() {
return 2 * super.area() + super.perimeter() * this.height;
}
public double volume() {
return super.area() * this.height;
}
}
X5_3_6.java主类代码
public class X5_3_6 {
public static void main(String[] args) {
Circle cir1 = new Circle(5);
System.out.println("圆的面积为：" + cir1.area());
System.out.println("圆的周长为：" + cir1.perimeter());
Cylinder cy1 = new Cylinder(10, 15);
System.out.println("圆柱体的表面积为：" + cy1.area());
System.out.println("圆柱体的体积为：" + cy1.volume());
}
}
上面是我写的代码，下图是执行结果，麻烦看一下，是否可以。
