Ternary operator, array method and integer comparison code in Java

//class前，导入的java包import java.util.Scanner; //我只把主方法列出来了 public static void main(String[] args) { Scanner scanner = new Scanner(System.in); // 接收用户输入 System.out.println("清输入第1个数："); int a = scanner.nextInt(); System.out.println("清输入第2个数："); int b = scanner.nextInt(); System.out.println("清输入第3个数："); int c = scanner.nextInt(); System.out.println("清输入第4个数："); int d = scanner.nextInt(); // 三目运算解决 int m = a > b ? a : b; int n = c > d ? c : d; int x = m > n ? m : n; System.out.println("max=" + x); // 分支方法解决 int t; if (a > b) { t = a; a = b; b = t; } if (a > c) { t = a; a = c; c = t; } if (a > d) { t = a; a = d; d = t; } if (b > c) { t = b; b = c; c = t; } if (b > d) { t = b; b = d; d = t; } if (c > d) { t = c; c = d; d = t; } System.out.println("max=" + d); // 数组方法解决 int p[] = new int[4]; for (int i = 0; i < 4; i++) { System.out.println("请输入第" + (i + 1) + "个数字："); p[i] = scanner.nextInt(); } for (int i = 0; i < 3; i++) { if (p[i] > p[i + 1]) { // 这里也可以设置一个中间变量t来进行交换 p[i] = p[i] + p[i + 1]; p[i + 1] = p[i] - p[i + 1]; p[i] = p[i] - p[i - 1]; } } System.out.println("max=" + p[3]);// 最大的就放在数组最后了 }
