填空题 程序填空题:编写方法,按升序显示三个数.编写测试程序,提示用户输入三个整数,调用方法以升序显示它们. public class Sort { public static void main(String[] args) { Scanner scan=new Scanner(System.in); System.out.print("请输入三个整数:"); int num1=scan.nextInt(); int num2=scan.nextInt(); int num3=scan.nextInt(); System.out.printf("%d,%d,%d\n",num1,num2,num3); displaySortedNum(num1,num2,num3); } public static void displaySortedNum(int num1, int num2, int num3) { if(num1>num2){ int temp=num1; num1=num2; num2=temp; } if(num2>num3){ int temp=num2; num2=num3; num3=temp; } if( 1 ){ int temp= 2 ; 3 =num2; num2=temp; } System.out.printf("%d,%d,%d\n",num1,num2,num3); } }
