Eclipse 答疑：为什么在 Eclipse 中，运行本程序却是另外一个程序的结果？

package review3_31;

public class SwitchToIfElseWithSwitch {
	public static void main(String[] args) {
		int x = 1,a = 3;
		switch(a) {
		case 1: x += 5;
			break;
		case 2: x += 10;
			break;
		case 3: x += 16;
			break;
		case 4: x += 34;
		}
		System.out.println(x);
	}
}

package review3_32;

import java.util.Scanner;

public class ComputeDayWithSwitch {
	public static void mian(String[] args) {
		Scanner input = new Scanner(System.in);
		System.out.print("Please enter a day in integer:");
