Need help with java code can't find my mistake went through it couple of times

[hallow pumice]

public static void getGrades() {
final int gradeT1 = inputInt("What is your 1st theory grade? 1) A+ 2) A 3) B 4) C 5) D 6) F 7) G");
final int gradeD1 = inputInt("What is your 1st dry run grade? 1) A+ 2) A 3) B 4) C 5) D 6) F 7) G");
final int gradeP1 = inputInt("What is your 1st program grade? 1) A+ 2) A 3) B 4) C 5) D 6) F 7) G");

String letterT1 = assignGrades(gradeT1);
String letterD1 = assignGrades(gradeD1);
String letterP1 = assignGrades(gradeP1);

System.out.println("Your grades were " + letterT1 + " " + letterD1 + " " + letterP1);

int gradeT2 = inputInt("What is your 1st theory grade? 1) A+ 2) A 3) B 4) C 5) D 6) F 7) G");
int gradeD2 = inputInt("What is your 1st dry run grade? 1) A+ 2) A 3) B 4) C 5) D 6) F 7) G");
int gradeP2 = inputIn("What is your 1st program grade? 1) A+ 2) A 3) B 4) C 5) D 6) F 7) G");

String letterT2 = assignGrades(gradeT2);
String letterD2 = assignGrades(gradeD2);
String letterP2 = assignGrades(gradeP2);

System.out.println("Your grades were " + letterT2 + " " + letterD2 + " " + letterP2);

String letterT3 = "";
String letterD3 = "";
String letterP3 = "";

if (gradeT1 > gradeT2) {
    letterT3 = letterT2;
} else { 
    letterT3 = letterT1;
}
if (gradeD1 > gradeD2)
{

letterD3 = letterD2;
}
else
{
letterD3 = letterD1;
}

if (gradeP1 > gradeP2) {
letterP3 = letterP2;
}
else {
letterP3 = letterP1;
}
System.out.println("Your final three test grades are " + "Theory: " + letterT3 + ", " + "Dry Run: " + letterD3 + ", " + "Program: " + letterP3 + ".");
}

theres a mistake in this code been trying to find it

its not running

Unresolved dependencies:

• method inputInt(java.lang.String)
• method assignGrades(int) THE ERROR

Please put it in a code block

Better yet, please read #📄・posting-guidelines

I don't know of an "inputInt" function in Java, does it exist?
the usual way to take the user input is through the scanner class

import java.util.Scanner;

Scanner in = new Scanner(System.in);
int num = in.nextInt();

also, you may make it less cluncky to use by either accepting the grade as char ("A", "B", "C"...) or by number

what is the function assignGrade? this seems to be needlessly complicated, maybe could we improve a lot on this code
