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

int sum = 0;

int c = 0;

{

int b = (int) Math.pow(10, j);

c = i / b;

System.out.println(c);

sum += c;

System.out.println("sum=" + sum);

i %= b;

System.out.println(sum);

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。

java线程的经典代码

private String name;

private int delay;

public ThreadDemo3(String sname, int i_delay) {

}

public void run() {

try {

sleep(delay);

} catch (InterruptedException e) {

}

System.out.println("多线程测试！\n" + name + "\n" + delay);

}

}

public class testMyThread {

public static void main(String[] args) {

ThreadDemo3 th1,th2,th3;

th1 = new ThreadDemo3("线程1", (int) (Math.random() * 900));

th2 = new ThreadDemo3("线程2", (int) (Math.random() * 900));

th3 = new ThreadDemo3("线程3", (int) (Math.random() * 900));

th1.start();

th2.start();

th3.start();

}

}

package threadgroup;

public class threadDemo {

public static void main(String[] args) {

Thread t = Thread.currentThread();

t.setName("你好吗？");

System.out.println("正在进行的Thread是：" + t);

try {

for (int i = 0; i 5; i++) {

System.out.println("我不叫穆继超" + i);

Thread.sleep(3000);

}

} catch (Exception e) {

// TODO: handle exception

System.out.println("Thread has wrong" + e.getMessage());

}

}

}

package threadgroup;

public class threadDemo2 implements Runnable {

public threadDemo2() {

Thread t1 = Thread.currentThread();

t1.setName("第一个主进程");

System.out.println("正在运行" + t1);

Thread t2 = new Thread(this, "");

System.out.println("在创建一个进程");

t2.start();

try {

System.out.println("使他进入第一个睡眠状态");

Thread.sleep(2000);

} catch (InterruptedException e) {

System.out.println("Thread has wrong" + e.getMessage());

}

System.out.println("退出第一个进程");

}

public void run() {

try {

for (int i = 0; i 5; i++) {

System.out.println("进程" + i);

Thread.sleep(3000);

}

} catch (InterruptedException e) {

}

System.out.println("退出第二个进程");

}

public static void main(String[] args) {
