Job learning objectives	For class to class teaching methods and teacher requirements, course of study to master the necessary software tools; Understand JVM, JRE and JDK concepts, learn to download, install, test JDK; Master PATH, CLASSPATH system variable effect and sets; Master the command-line compiler and run a Java program steps; Master the Java Application Program Structure characteristics; Master the steps to develop Java programs run under JDK command line. The initial use of Elipse, learn to compile, run, debug simple Java Application program.

Part II: theoretical knowledge and learning part:

1. Experiment name: experiment a Java programming environment

2. Purpose:

(1) Installation and configuration of JDK master;

(2) master the basic commands and steps to use JDK develop Java programs;

(3) proficiency in the use Elipse integrated development environment for developing the basic steps java program

(4) master the basic syntax of Java programs.

3. Experimental procedure and content:

Experiment 1 JDK installation and configuration (10 minutes)

 

 Experiment 2 download textbook example of package:

 

 Experiment 3 command-line compiler run Welcome.java program:

 

 Experiment 4 with JDK command-line development HelloWorld! program:

1. Code:

public class Hello
{
public static void main(String[] args)
{
String greeting = "Hello Java World!";
System.out.println(greeting);
for (int i = 0; i < greeting.length(); i++)
System.out.print("=");
System.out.println();
}
}

 

2. Compile the results:

 

 

 Experiment 5 download and install Eclipse integrated development package:

 

 Experiment 6 using the Eclipse development program output the multiplication table:

1. Code:

package first;

public class chenfabiao {

public static void main(String[] args) {
// TODO Auto-generated method stub
for(int i=1;i<10;i++)
{
for(int j=1;j<=i;j++)
{
int k;
k=i*j;
System.out.printf("%d*%d=%d ",j,i,k);
}
System.out.println();
}

}

}

2. Run Results:

 

 4. Experimental Summary:

          By the first week of learning, the teacher in the class learned that the way to master the courses necessary software tools; learn to download, install, test JDK, and in and on your machine installed JDK, configure the environment; use the command line compile and run the first java program "Welcome"; Elipse initial use of the integrated development software, completed the first program I have written "multiplication table", and compile and run. Through this learning gradually feel the benefits of java language, which had a strong interest.
