编写一个程序，实现从命令行参数输入一字符串，统计该字符串中字符输入字符的出现的次数。

package pro1214test;

import java.util.Scanner;

public class eCiShu {
	public static void main(String[] args) {
		Scanner s = new Scanner(System.in);
		System.out.println("请输入一串字符");
		String t = s.next();
		System.out.println("请输入要查询次数的字符");
		 String t1=s.next();
		String y = null;
		String[] A = new String[t.length()];
		for (int o = 0; o < t.length(); o++) {
			A[o] = t.substring(o, o + 1);
			//System.out.println(A[o]);
		}
		s(A, t1);
		//System.out.println(s(A, t1));
		int l=0;
		if(A[0].equals(t1)) {
			l++;
		}if(A[A.length-1].equals(t1)) {
			l++;
		}
		System.out.println("字符"+t1+"在"+t+"中出现的次数为"+(s(A, t1)+l));
	}
	static int s(String[]A,String t1) {
		int count = 0;
		for (int p = 0; p < A.length; p++) {
			for (int q = 1; q < A.length - 1; q++) {
				if (A[p] == (A[q]) && A[p].equals(t1+"")) {
					// System.out.println("p的值为"+A[p]+",q的值为"+A[q]);
					count++;
					//System.out.println(count);
				}
			}
			
		}return count;
}}
