1.使用Scanner
使用時需要引入套件import java.util.Scanner;首先定義Scanner物件
Scanner sc = new Scanner(System.in);
如果要輸入整數，則int n = sc.nextInt( );
String類型的，則String temp = sc.next();
例如：
import java.util.Scanner;
public class Test {
@SuppressWarnings("resource")
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.println(scanner.next());
}
}2.使用BufferedReader
用前需要引入import java.io.Reader;
用前需要引入import java.io.Reader;
String input = br.readLine();
例如：
import java.io.*;
public class Test {
public static void main(String[] args) {
try {
BufferedReader br = new BufferedReader(new InputStreamReader(
System.in));
System.out.println(br.readLine());
} catch (IOException e) {
}
}
}
