sc.next()和 sc.nextLine() 以回車為結束符

import java.util.Scanner;

public class test0101 {
    public static void main(String[] args) {
        System.out.print("輸入：");

        Scanner sc = new Scanner(System.in);

        String s = sc.next();
        //String s = sc.nextLine();

        System.
 
out.println("輸出：" + s);
    }
}

sc.nextInt()以空格為結束符
若錄入其他符號比如",""."會直接報錯

import java.util.Scanner;

public class test0101 {
    public static void main(String[] args) {
        System.out.print("輸入：");

        Scanner sc = new Scanner(System.in);

        int
 
 s = sc.nextInt();

        System.out.println("輸出：" + s);
    }
}

sc.useDelimiter(",")+sc.nextInt()以逗號結束

import java.util.Scanner;

public class test0101 {
    public static void main(String[] args) {
        System.out.print("輸入：");

        Scanner sc = new Scanner(
 
System.in);

        sc.useDelimiter(",");

        int s = sc.nextInt();

        System.out.println("輸出：" + s);
    }
}

sc.useDelimiter(",")+sc.next()以逗號結束

import java.util.Scanner;

public class test0101 {
    public static void main(String[] args) {
        System.out.print("輸入：");

        Scanner sc = new Scanner(System.in);

        sc.useDelimiter(",");

        String s = sc.next();

        System.out.println("輸出：" + s);
    }
}

sc.useDelimiter(",")+sc.nextLine()以回車結束

import java.util.Scanner;

public class test0101 {
    public static void main(String[] args) {
        System.out.print("輸入：");

        Scanner sc = new Scanner(System.in);

        sc.useDelimiter(",");

        String s = sc.nextLine();

        System.out.println("輸出：" + s);
    }
