package scanner;
import java.util.Scanner;
public class Demo01 {
public static void main(String[] args) {
scanner();
scanner2();
scanner3();
}
public static void scanner(){
Scanner scanner = new Scanner(System.in);
System.out.println("next方式接收:");
if (scanner.hasNext()){
String str= scanner.next() ;
System.out.println("输入内容为:"+str);
}
// scanner.close();
}
public static void scanner2(){
Scanner scanner = new Scanner(System.in);
System.out.println("nextLine方式接收:");
if (scanner.hasNextLine()){
String srt=scanner.nextLine();
System.out.println("输入内容为:"+srt);
}
// scanner.close();
}
public static void scanner3(){
Scanner scanner = new Scanner(System.in);
System.out.println("请输入数据 :");
String str = scanner.next();
System.out.println("next===>输入内容为:"+str);
String res = scanner.nextLine();
System.out.println("nextLine==>输入内容为:"+res);
scanner.close();
}
}
运行结果
