实验12 部署applet和应用程序
一、实验目的
练习Java中部署applet和应用程序的应用。
二、实验内容
Program 1 Purpose:
Familiarize yourself with some of Java's GUI capabilities and event handling and write a program containing these things.
Program:
Create a program to do display something close to the following: ----------------------------------- | Input Numbers | | ----------------------------- |
| | | | <<< This is a text field | ----------------------------- | | | | -------------------- |
| | Sort low to high | | <<< This is a button | -------------------- | | | | -------------------- |
| | Sort high to low | | <<< This is a button | -------------------- | | | | | | Output Numbers | | ----------------------------- |
| | | | <<< This is a text field | ----------------------------- | | | | | | -------------------- |
| | Exit Program | | <<< This is a button | -------------------- | | |

-----------------------------------
You will be provided with a method that takes in a String and returns to you an array of integers. ( I will write this and make it available to you. ) The String that you pass in is the one the user enters in the \numbers\text field.
You will need to have a method to sort the array that is returned (you can use bubblesort just like in the last couple of labs.) This will sort from low to high. If you do copy it out of the book, just give proper attribution.
When the \low to high\button is clicked, you should output the sorted integers in the \
When the \high to low\button is clicked, you should output the sorted integers in the \
The user should be able to change the numbers in the \and when the buttons are pressed, they sort the current numbers and output them sorted.
