【问题描述】:
我有一个用于点球大战的 Java 程序,我想将 b1、b2、b3 和 s1 限制为 1-9 之间的任何数字。如果输入不等于 1-9 再试一次。
for (int i=0;i<=5;i++)
{
int b1, b2, b3, s1;
int j=i+1;
System.out.println("Enter the Numbers which you will block.... Please remember that it should be from 1-9 and nothingelse, 1 2 3 4 5 6 7 8 9");
b1=Integer.parseInt(br.readLine()); // how to restrict this to numbers between 1 to 9
b2=Integer.parseInt(br.readLine()); //this also
b3=Integer.parseInt(br.readLine()); //this also
System.out.flush();
System.out.println("Enter The Number where you will score");
s1=Integer.parseInt(br.readLine()); //this also
