[JAVA] 於不同package間導入數值

※ 此程式碼並非優化版本，僅供個人學習用途，若有任何問題請告知。


程式碼如下：

	package main;
	import test.test;
	public class abc {
	public static void pint(int n) { //print something integer
	System.out.print(n+"　");
	}
	public static void pdouble(double n) {//print something double
	System.out.print(n+" ");
	}
	public static void pstr(String str) { //print something
	System.out.println(str);
	}
	public static void sint(int i, int j) { //swap something integer
	test.i = j;
	test.j = i;
	}
	public static void sdouble(double i, double j) { //swap something double
	double temp = i;
	i = j;
	j = temp;
	}
	}

	package test;
	import main.*;
	public class test {
	public static int i = 10, j = 20;
	public static void main(String args[]){
	String str1 = "abc";
	abc.pstr(str1);
	abc.sint(i,j);
	abc.pint(i);
	abc.pint(j);
	}
	}

結果如下：
