Question

用java编写程序实现比较两个数的大小，输出比较结果，比如输入5,3，输出5比3大。

Answer 1

public class Demo1 {
public static void main(String[] args) {
// TODO Auto-generated method stub
Scanner s1 = new Scanner(System.in);
System.out.println("请输入第一个数字：");
int a = Integer.parseInt(s1.nextLine());

Scanner s2 = new Scanner(System.in);
System.out.println("请输入第二个数字：");
int b = Integer.parseInt(s1.nextLine());

if(a>b){
System.out.println(a+"比"+b+"大");
}
}
}

Answer 2

public static void main(String args[]){
java.util.Scanner sc=new java.util.Scanner(System.in);

double a=sc.readDouble();
double b=sc.readDouble();
double tmp=a;
if(a<b) {
a=b;b=tmp;}
System.out.println(a+"比"+b+"大");
}
}

Answer 3

public static void main(String[] args) {
try {
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
System.out.println("请输入数字:");
String a=br.readLine();
System.out.println("请输入另一数字:");
String b=br.readLine();
System.out.println((Integer.parseInt(a) > Integer.parseInt(b) ? a + "大于" + b:a+"小于" + b));
} catch (NumberFormatException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}

Answer 4

System.out.println(a>b?a+"比"+b+“大";b+"比"+a+"大")
