Create a java program that takes the input as student name g

Create a java program that takes the input as student name, grade point Avg. Ask the user to enter fivestudent names with grades using the scanner class. Please use the concept of stack to store all the student information.  Once you store five students, display two options 1 MinGrade 2 Avg grade.

If the user enters 1, then print min grade and if the user enters 2, then print Avg class grade.

Solution

Please follow the code and comments for description :

CODE :

import java.util.*; // required imports

public class minAndAvgGrades { // class to run the code

public static void main(String[] args) { // driver method
Scanner sc = new Scanner(System.in); // scanner class to get the data
Stack<String> namestack = new Stack<>(); // required stack objects
Stack<Integer> gradestack = new Stack<>();
for (int i = 0; i < 5; i++) { // iterate over the data and save the values
System.out.println(\"Enter the Name of the Student : \"); // message prompt
String name = sc.nextLine(); // get the data
sc.nextLine();
namestack.push(name); // add the dat to the stack
System.out.println(\"Enter the Grade of the Student : \"); // messaeg prompt
int number = sc.nextInt(); // get the data
gradestack.push(number); // add the data to the stack
}
System.out.println(\"\ You have the Below Choices..\"); // print the choices
System.out.println(\"1.Minimum Grade.\");
System.out.println(\"2.Average Grade.\");
int choice = sc.nextInt(); // get the choice

switch (choice) { // switch over the choices
case 1:
System.out.println(\"Calculating the Minimum Grade of the Students..\"); // message
int min = gradestack.firstElement(); // get the first element
for (int i = 1; i <= 5; i++) {
if (gradestack.peek() < min) { // check for the minimu value
min = gradestack.pop(); // pop the value
} else {
gradestack.pop();
}
}
System.out.println(\"The Minimum Grade of the Information is : \" + min); // message
break;
case 2:
System.out.println(\"Calculating the Average Grade of the Students..\"); // message
int sum = 0; // local variables
while (!gradestack.isEmpty()) { // check for the empty
sum = sum + gradestack.pop(); // sum up the values
}
double avg = sum / 5;
System.out.println(\"The Average grades for the Information is : \" + avg); // get the avrage to console
break;
default:
System.out.println(\"Invalid Selection.!\"); // default choice
System.exit(0);
break;
}
}
}
