1.写返回类型
2.return 返回值
3.定义变量接受返回值
public class App2 { public String [] print(String msg, int num) { for (int i = 0; i < num; i++) { System.out.println(msg); } return new String[]{"aaa","bbb"}; } public static void main(String[] args) { App2 obj = new App2(); String[] x = obj.print("hello world", 5); System.out.println(x[0]); System.out.println(x[1]); } }
执行结果:
hello world hello world hello world hello world hello world aaa bbb
