PackageTest

milan25429688

这是我第一个Package 包相关类的测试例子，分为三部分：MainTest 、PackageSecond 和PackageSub

1。MainTest

路径：PackageTest\com\xzm\maintest

package com.xzm.maintest;

import com.xzm.pksub.*;
import com.xzm.pksecond.*;

public class Main
{
public static void main(String[] args)
{
PackageSecond second = new PackageSecond("I am in Main");
second.printvalue();

PackageSub sub = new PackageSub("I am in Main");
sub.printvalue();

System.exit(0);
}
}

2。PackageSecond

路径：PackageTest\com\xzm\pksecond

package com.xzm.pksecond;

public class PackageSecond
{
private String value;

public PackageSecond(String s)
{
value = s;
}

public void printvalue()
{
System.out.println("value of PackageSecond is " + value);
}
}

3。PackageSub

路径：PackageTest\com\xzm\pksub

package com.xzm.pksub;

import com.xzm.pksecond.*;

public class PackageSub
{
private String value;

public PackageSub(String s)
{
value = s;
}

public void printvalue()
{
PackageSecond second = new PackageSecond("I am in subpackage.");
second.printvalue();

System.out.println("value of PackageSub is " + value);
}

}
