在eclipse中对于java的操作
1. 新建project
new project --> java project -->input the name of the project and choose the jre -- press the button"New Java Package"--> input the package's name -->under the package, press the "New Java Class" button
下面这是一个小程序,project :HelloWorld , package name:helloworldtest , class name:Exercise
package helloworldtest; public class Exercise { public static void main(String args[]){ System.out.println("hello wang. This is java"); } }
