​public static void main(String[] args) {
		//定义一个字符数组ch并初始化
		char[] ch= new char[10];
		  System.out.print("input your char:");
		    Scanner sc = new Scanner(System.in);
		    String str = sc.next();
		for(int i=0;i<ch.length;i++){
		    ch[i]=str.charAt(i);
		}
		for(char n:ch){
		    System.out.println("oriangal arry:"+n);
		}

		//循环遍历数组，统计字符’a’或’A’出现的次数
		 int count=0;
		 for(int i=0;i<ch.length;i++){

		     if(ch[i]=='a' || ch[i]=='A'){
