模拟银行账户存、取款，转账功能

在模拟银行过程中注意： 1.不支持的操作要抛异常 2.时间要用LoaclDate 3.方法中不能有输出

java求斐波那契额数列

public static void main(String[] args) { int[] f = new int[20]; f[0] = 1; f[1] = 1; System.out.println("第1项为" + f[0]); System.out.println("第2项为" + f[1]); for (int i = 2; i < 20; i++) { int j = i + 1; f[i] = f[i - 1] + f[i - 2]; System.out.println("第" + j + "项为" + f[i]); } }

java求平均数和大于平均数的数

核心部分： int count; static double average; static double value[]; static double sum = 0; public static void main(String args[]) { Scanner sc = new Scanner(System.in); int count = sc.nextInt(); double[] value = new double[count]; for (int i = 0; i < count; i++) { value[i] = sc.nextDouble(); sum = sum + value[i]; } sc.close(); average = sum / count; for (int i = 0; i < count; i++) { if (value[i] > average) { System.out.println("大于平均数的数" + value[i]); } }
