Develop a Java application that will determine whether any of several department-store customers has exceeded the credit limit on a charge account.
For each customer, the following facts are available:
a) account number
b) available balance at the beginning of the month
c) total of payments by the customer this month
d) total of all credits applied to the customer’s account this month
e) allowed credit limit.
The program should input all these facts as integers, calculate the new available balance (= beginning balance + payments – credits), display the new available balance and determine whether the new balance exceeds the customer’s credit limit. For those customers whose credit limit is exceeded, the program should display
the message "Credit limit exceeded".

Answers have more impact when displayed visually. Write an application that
displays the distances one can travel on a full tank of gasoline at di®erent
velocities. Use this formula to calculate distance travelled for a positive velocity,
v:
distance = (40 + 0:05v ¡ (0:06v)
2
) ¤ capacity
where capacity is the size of the automobile's fuel tank. (Note: This simplistic
formula assumes that the car has a one-gear transmission.)
The input to the application is the fuel tank's size; the output are the distances
travelled (and the time taken to do so) for velocities 20, 40, 60, 80, and 100 miles
per hour. Display the answers graphically, so that the answers are pictures like
this:
For a 10-gallon fuel tank:
/A CAR\
40 m.p.h.: =================== -o--o-- 362.4 miles in 9.06 hours
/A CAR\
60 m.p.h.: =============== -o--o-- 300.4 miles in 5.007 hours

Write a Java program to fill an array of integers with 1000 randomly generated integers and sorts these numbers using selection sort. Then the program asks the user to choose a number and searches for this number in the array using the well-known Sequential Search Algorithm described in class. If found then the program prints its location in the array, if not then the program prints a message saying that the target was not found in the array

Write a Java program to:
o Read an integer N <= 50,
and read N long integers into array ID and
N float numbers into array Score of size 50;
These two arrays represent the ID numbers and the scores of N students in a class;
o Find the maximum score, MaxScore, of students in this class;
o Compute the Percent array such that Percent[I] = 100.0 *Score[I] / MaxScore
for I=1,……,N;
o Print a three columns table with headings ID Number, Score, Percentage for three arrays ID, Score, and Percent respectively. Use formatted output.
You should write and use the following methods in your program:
Method readArray that reads the first N entries of arrays ID and Scores.
Method findMax that returns the maximum entry for the first N cells of array Scores.
