零基础学JAVA DAY1

 今天周六，果然是没什么学习的兴致。心里知道学习的重要性却坚定不了决心去学。哎，勉强看了一会儿翁恺老师教的课程，现在补一下留的作业吧。说是零基础学JAVA，好歹也拿了计算机科学与技术的学士学位证，也没那么废物吧（苦笑）。作业1代码贴在下面，以后代码还是要自己写的，从基础开始吧。
 作业1

public class TemperatureTransfer {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        int a = in.nextInt();
        double b = 9 / 5.0;
        double c = (a - 32)/ b;
        System.out.println((int)c);
    }
}

 作业2.1

import java.util.Scanner;

public class TimeTransfer{
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        int bjt = in.nextInt();
        int minute = bjt % 100;
        int hour = bjt / 100;
        int utc = 0;
        if(hour < 8){
            utc = (hour - 8 + 24) * 100 + minute;
        }
        if(hour == 8){
            utc = minute;
        }
        if(hour > 8){
            utc = (hour - 8) * 100 + minute;
        }
        System.out.println(utc);

    }
}

 作业2.2

import java.util.Scanner;

public class SignalReport {
    public static void main(String[] args){
        Scanner in = new Scanner(System.in);
        int a = in.nextInt();
        int R = a / 10;
        int S = a % 10;
        switch (S){
            case 1 :
                System.out.print("Faint signals, barely perceptible");
                break;
            case 2 :
                System.out.print("Very weak signals");
                break;
            case 3 :
                System.out.print("Weak signals");
                break;
            case 4 :
                System.out.print("Fair signals");
                break;
            case 5 :
                System.out.print("Fairly good signals");
                break;
            case 6 :
                System.out.print("Good signals");
                break;
            case 7 :
                System.out.print("Moderately strong signals");
                break;
            case 8 :
                System.out.print("Strong signals");
                break;
            case 9 :
                System.out.print("Extremely strong signals");
                break;
            default:
                break;
        }
        System.out.print(", ");
        switch (R){
            case 1 :
                System.out.print("unreadable");
                break;
            case 2 :
                System.out.print("barely readable, occasional words distinguishable");
                break;
            case 3 :
                System.out.print("readable with considerable difficulty");
                break;
            case 4 :
                System.out.print("readable with practically no difficulty");
                break;
            case 5 :
                System.out.print("perfectly readable");
                break;
            default :
                break;
        }
        System.out.print(".");
    }
}

 哎，不用功啊，就这几个程序摆出来，怕是被别人笑话。没办法，从最基础的开始练习吧。
