 Write a java program that accepts a given n, then create a 2D array with n rows and n columns. Then for each cell the value should be n+row to the power column. For example if we talk of n=5, then array[0][0] =(5+0)⁰  = 1. Print out all the values in the array created.

Write a Java program to simulate an online store. The program should begin by displaying a list of products and their prices. There should be a minimum of 4 products offered. The program should ask the user to choose a product and then ask the user to enter the quantity they require of that product. The program should then allow the user to keep choosing more products and quantities until they enter something to indicate they want to end the program (e.g. a given number or ‘q’ or ‘exit’). The program should then tell the user the total amount for the products they have selected. Students must use array or arraylist to store the products and their prices.

We want to calculate the total marks of each student of a class in Physics, Chemistry and Mathematics and the average marks of the class. The number of students in the class are entered by the user. Create a class named Marks with data members for roll number, name and marks. Create three other classes inheriting the Marks class, namely Physics, Chemistry and Mathematics, which are used to define marks in individual subject of each student. Roll number of each student will be generated automatically.

USING IF ELSE CONDITIONAL STATEMENT

Write a JAVA program that will input Employee Name, Rate per hour, No. of hours worked 

and will compute the daily wage of an employee. If the number of hours worked exceeds 

eight hours add 30% to each excess hour as overtime rate. 

Formula: Daily Wage = Rate per hour * No. of hours worked + OT pay

IF ELSE CONDITIONAL STATEMENT

Write a JAVA program that will input the following data: Student Name, Average, Tuition Fee 

and output Total Tuition Fee. 

Formula: Total Tuition Fee = Tuition Fee – Discount 

If average is: 95 – 100 100% discount 

 90 – 94 25% 

 85 – 89 10% 

 84 and below no discount
