递归调用的例子:
/*** 99瓶啤酒*/public class ConditionTest16 {public static void main(String[] args) {game(99);}public static void game(int num){System.out.println(num+"瓶啤酒在墙上,"+num+"瓶啤酒,传给他人");num=num-1;if (num == 0){System.out.println("没有啤酒在墙上,没有啤酒,不能再拿了,不能在再传了,因为墙上没有啤酒了");return;//返回语句}game(num);//自己调用自己}}
条件语句以及逻辑语句的例子:
public class Test56 {public static void main(String[] args) {int amount = compute(20000, 1500, true, true, true);System.out.println(amount);amount = compute(40000, 1500, true, true, true);System.out.println(amount);}/*** 计算个人缴纳的个税** @param income 工资收入* @param socialSecurity 5险一金金额* @param onlyChild 是否独生子女* @param hasChild 是否有小孩在读书* @param hasParents 是否有60岁以上的父母需要赡养* @return*/public static int compute(int income, int socialSecurity, boolean onlyChild, boolean hasChild, boolean hasParents) {int total = income - 5000 - socialSecurity;if (hasChild) {total = total - 1000;}if (hasParents && onlyChild) {total = total - 2000;}if (total >= 3000 && total < 12000) {total = total * 10 / 100 - 210;} else if (total >= 12000 && total < 25000) {total = total * 20 / 100 - 1410;} else if (total >= 25000 && total < 35000) {total = total * 25 / 100 - 2660;}return total;}}
