简单方法找出A数组有B数组没有的值

public static void main(String[] args) {
		
		String a[]=new String[]{"a","b","c","e"};
		String b[]=new String[]{"b","c","d"};
		
		for (int i = 0; i < a.length; i++) {
			boolean isEq=false;
			for (int j = 0; j < b.length; j++) {
				if (a[i].equals(b[j])) {
					isEq=true;
					break;
				}
			}
			if (!isEq) {
				System.out.println(a[i]);
			}
		}
	}
