What I originally planned was to be like a very, very basic calculator
It is possible to calculate various formulas, but there is no program error.
If you enter the formula, the result will not come out and no value will come out.
I'd appreciate it if you could point out which part went wrong.
Example: If you enter 3 + 5 * 6 / 5, the result should come out
There's just a blank. Masters, please!
package main;
import java.util.Scanner;
public class Main4 {
public static void main(String[] args) {
// // TODO Auto-generated method stub
System.out.print ("Enter Formula");
Scanner s = new Scanner(System.in);
int x = s.nextInt();
while(true)
{
String ops = s.next();
if (ops == null)
{
break;
}
char op = ops.charAt(0);
int y = s.nextInt();
int z = 0;
switch(op)
{
case '+':
x += y;
break;
case '-':
x -= y;
break;
case '*':
x *= y;
break;
case '/':
x /= y;
break;
case '%':
x %=y;
break;
default:
System.out.println ("Input Error");
}
}
System.out.println(x);
}
}

Did you enter "3 + 5 * 6 / 5" at once?
Looking at the code, you have to enter only one letter at a time after entering '3', '+', and then '5'.
You said you didn't get any results and no value, but the program probably stopped waiting for input.
We recommend that you kindly write a notice with a print statement for each part you receive. :)
public static void main(String[] args) {
Scanner s = new Scanner(System.in);
System.out.print ("Enter the first digit");
int x = s.nextInt();
System.out.print ("Enter Operator");
String ops = s.next();
System.out.print ("Enter a second digit");
int y = s.nextInt();
if (ops == null){
System.out.print ("No operator");
return;
}
char op = ops.charAt(0);
switch(op) {
case '+':
x += y;
break;
case '-':
x -= y;
break;
case '*':
x *= y;
break;
case '/':
x /= y;
break;
case '%':
x %=y;
break;
default:
System.out.println ("Input Error");
}
System.out.println(x);
}
