How to limit input integers from 1 to 9
I have a Java program to play the playoffs, I want to limit b1, b2, b3 and s1 to any number only from 1-9. If the input is not 1-9, try again.
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

Try this dynamic way,
public class testJava {
public static void main(String[] args) {
testJava j = new testJava();
System.out.println(j.isBetween(1,1,9));
}
public boolean isNumeric(int value,int startValue,int endValue) {
if(value >= startValue || value <= endValue)
{
return true;
}else{
return false;
}
}
}
