1.不使用中間變量交換兩個數
public class Exchange { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); System.out.Exchange 2.利用三目運算符判斷奇偶性
public class ParityCheck { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); System.out.println("請輸入一個整數："); Long num = scanner.nextLong(); String s = (num%2==0)?"這個數是：偶數":"這個數是：奇數"; System.out.println(s); }}ParityCheck
