为什么我用nextInt会报错
package java.uyil;
//import java.util.Scanner;
import java.util.*;
//import java.
public class Scanner {
public static void main(String[]args){
Scanner scanner= new Scanner();
System.out.print("请输入学生年龄：");
int ageOfStudent = scanner.nextInt();
System.out.println("该生是否满18岁?"+
(ageOfStudent>=18?"yes":"no"));
}
}
package java.uyil;
//import java.util.Scanner;
import java.util.*;
//import java.
public class Test {
public static void main(String[]args){
Scanner scanner= new Scanner(System.in);
System.out.print("请输入学生年龄：");
int ageOfStudent = scanner.nextInt();
System.out.println("该生是否满18岁?"+
(ageOfStudent>=18?"yes":"no"));
}
}
Scanner scanner= new Scanner(System.in);你要输入整数才可以
package java1.a;
//import java.util.Scanner;
import java.util.*;
//import java.
public class Test {
public static void main(String[]args){
Scanner scanner= new Scanner(System.in);
System.out.print("请输入学生年龄：");
int ageOfStudent = scanner.nextInt();
System.out.println("该生是否满18岁?"+
(ageOfStudent>=18?"yes":"no"));
}
}追问
提示编辑器不包含一个主要类型
追答包名java1.a
你用下面这个代码吧
package java1.a;
import java.util.*;
public class Test {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.print("Please input the age for a student:");
int ageOfStudent = scanner.nextInt();
System.out.println("Is greater than 18?"+ (ageOfStudent >= 18 ? "yes" : "no"));
}
}
public static void main(String[]args){
Scanner scanner= new Scanner(System.in);
System.out.print("请输入学生年龄：");
int ageOfStudent = scanner.nextInt();
System.out.println("该生是否满18岁?"+
(ageOfStudent>=18?"yes":"no"));
}
}
顺带注意类名本回答被网友采纳
加了 Scanner scanner= new Scanner(System.in); 这条也报错啦！
追答把你这类名改一下。。和Scanner重名了
