【Java 基础】不同类型的输入输出

import java.util.Scanner;
public class Main {
    public static void main(String[] args)
    {
        Scanner sc=new Scanner(System.in);//构建一个数据，输入对象
        byte a=10;
        short b=20;
        int c=30;
        long d=40L;
        float e=50F;
        double f=60D;
        char g='7';
        boolean h=true;
        double pi=3.14D;
        a=sc.nextByte();
        b=sc.nextShort();
        c=sc.nextInt();
        d=sc.nextLong();
        e=sc.nextFloat();
        f=sc.nextDouble();
        g=sc.next().charAt(0);
        h=sc.nextBoolean();
        pi=sc.nextDouble();
        System.out.println(a);
        System.out.println(b);
        System.out.println(c);
        System.out.println(d);
        System.out.println(e);
        System.out.println(f);
        System.out.println(g);
        System.out.println(h);
        System.out.println(pi);
    }
