Arrays
6.1 Introduction to arrays
Recommended Self-Test Exercises:
p 385-386: Ex. 1, 2, 4-6.
p 403-404: Ex. 13.
Lab Exercises:
Write an application that reads 10 grades, then displays the total, the average, the maximum and the minimum of those numbers.
Write an application that inputs 10 numbers, each between 0 and 100, then display the list of numbers without repetitions (duplicate values are not printed more than once).
For example: if the user enters 5 2 1 6 2 5 1 4 2 1,
The program should display: 5 2 1 6 4
Given an array of integers, write a java code that allows to check if the array is “palindromic”. A palindromic array is a symmetric one:
For example the arrays {1, 6, 4, 6, 1} and {2, 5, 8, 8, 5, 2} are both palindromic, but the array {3, 7, 5, 3} is not.
Write a program that reads a sequence of 10 integers into an array and then computes the alternating sum of all elements in the array:
For example if the array is : {1, 4, 9, 16, 9, 7, 4, 9, 11} then it computes : 1 - 4 + 9 - 16 + 9 - 7 + 4 - 9 + 11 = -2
Write a Java program to find the duplicate values of an array of integers
Write a Java program to find the common elements between two arrays (string values)
Write a Java program to find the second largest element in an array.
Write a Java program to add two integer arrays of the same size
