字符查找与统计

请修改编辑器中的代码，完成以下功能：在一个字符数组中查找指定的字符，然后将该字符在数组中出现过的所有位置以及出现的次数输出。程序的运行结果如下。 Found A at index 0 Found A at index 2 The total amount of A is 2 输出示例： Found A at index 0 Found A at index 2 The total amount of A is 2

public class Main {
    public static void main(String[] args) {
       //**********found**********
        _________ arrayOfChars = { 'A', 'B', 'A','D', 'E','F','G' };
        char searchfor = 'A';
        
        int i=0, j=0;
       //**********found**********
        while ( i < arrayOfChars.__________) {
            if (arrayOfChars[i] == searchfor) {
                System.out.println("Found " + searchfor + " at index " + i);
                j++;
	    }
       //**********found**********
	    ________________ ;
        }
       //**********found**********
        if (_______) {
	    	System.out.println("The total amount of " + searchfor + " is " + j );
        } else {
	    	System.out.println(searchfor + " is not in the array");
        }
    }
}
