输入一行字符，分别统计出包括英文字母、空格、数字和其他字符的个数

import java.util.Scanner;


public class GetNumDifChar {

	public static void main(String[] args) {
		Scanner scan = new Scanner(System.in);
		String str = scan.nextLine();
		int isLetter = 0;
		int isSpace = 0;
		int isDigit = 0;
		int isOther = 0;
		for (int i = 0; i < str.length(); i++) {
			if(Character.isLetter(str.charAt(i)))
				isLetter++;
			else if(Character.isSpace(str.charAt(i)))
				isSpace++;
			else if(Character.isDigit(str.charAt(i)))
				isDigit++;
			else 
				isOther++;
			
		}
		System.out.println(isLetter);
		System.out.println(isSpace);
		System.out.println(isDigit);
		System.out.println(isOther);
