public class ShunXunDemo01 { public static void main(String[] args) { System.out.println("hello1"); System.out.println("hello1"); System.out.println("hello1"); System.out.println("hello1"); System.out.println("hello1"); } }
按顺序打印出来
(if单选择结构)
import java.util.Scanner; public class IfDemo01 { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); System.out.println("请输入内容:"); String s = scanner.nextLine(); //equals:判断字符串是否相等 if (s.equals("Hello")){ System.out.println(s); } System.out.println("End"); scanner.close(); } }
判断字符串是否相等,输出的结果不一样
