class Student {
      String name;
      int grade;
       
      Student(String n, int g) {
            name = n;
            grade = g;
       }
}

public class TestStudent {
       public static void main (String[] args) {
                Student s1 = new Student ("John", 85);
                Student s2 = new Student ("Maria", 90);
                Student s3 = s2;

                s1.grade = 95;
                s3.name = "Ana";
 
                System.out.println(s1.name + " " + s1.grade);
                System.out.println(s2.name + " " + s2.grade);
                System.out.println(s3.name + " " + s3.grade);
        }
}

John 95

Instructions:

• Create a Java program based on the questions.
• Follow the exact required output shown in the question.
• You must use the specific operator required in each number.
• Show proper use of variables and correct operator usage.
• Follow proper Java syntax, indentation, and naming conventions.

Program Requirements:

1. Create a Java program named ATMWithdrawalLimit.
2. Assume the initial balance is 9,000 pesos.

===== ATM MENU =====

• 1. Check Balance
• 2. Deposit
• 3. Withdraw
• 4. Exit

Withdrawal Rules:

• Maximum withdrawal per transaction: 3,000 pesos
• If exceeded, display: Withdrawal Limit Exceeded

Use:

• if-else statements
• switch statement
• do-while loop

Program Requirements:

1. Create a Java program named: StudentPaymentSystemLastName (Example: StudentPaymentSystemBedis)
2. Ask the user to input:
   • Student Name
   • Student ID
   • Total Tuition Fee
3. Display the menu:

===== PAYMENT MENU =====

• 1. Pay Tuition
• 2. Check Balance
• 3. Apply Discount
• 4. Exit

Program Rules

General Rules

• Use switch statement to process menu options
• Use do-while loop to repeat the program until Exit
• Use nested if statements for validation
• Use a counter variable to track number of transactions

Payment Rules

1. Pay Tuition
   • Ask for payment amount
   • Validate:
     • If payment > remaining balance → display: Invalid Payment
     • Else → deduct from balance
   • Increment transaction counter
2. Check Balance

     • Discount applies only once
4. Exit
   • Display:
     • Student Name
     • Total Transactions
     • Final Balance
   • End program

Additional Conditions

• Prevent negative balance
• Prevent multiple discount applications
• Show message: No remaining balance if fully paid

Instructions:

1. Create a Java program named ExpenseTrackerLastName.
2. Implement the following methods:
   • A void method that displays the program title.
   • A non-void method that calculates the total expenses using three values:
     • food
     • transportation
     • other expenses
   • A non-void method that checks if the total expense exceeds a budget and returns a message.
   • A void method that displays the total expense and the budget status.
3. In the main method:
   • Call all the methods you created.
   • Display the final output clearly.
4. Use appropriate method names, parameters, and return types.
5. Add at least TWO enhancements:
   • Accept user input
   • Add another expense category
