Write a JAVA program
Write a function inside ProblemSolution class whose return type is void, accepts an array and the length of the array as input parameters. The function should call a static method display of MyArray class by passing an array and length value.
Input 5 1 5 8 2 0
Where,
First line of input represents the size of an array.
Second line represents array elements.
Output 1 5 8 2 0
Assume that,
N is an integer within the range [0 to 10000].
Array elements are integers within the range [-2147483648 to 2147483647].
2. write two method called findIndex and findLastIndex that search for a number in an array. they
should take an int array and an int as parameters. findIndex should return the index of the first
instance of the number in the array. findLastIndex should return the index of the last instance of
the number in the array. They both should return -1 if the number is not found. Do not use any
library methods.
Sample code
int a[]
int x = findIndex(a,50);
Sample output
{10,50,30, 40,50};
1
System.out.println(x);
int a[]
int x = findLastIndex (a,50);
System.out.println(x);
int a[] = {10,50,30,40,50};
int x = findIndex(a,70);
{10,50,30,40,50};

- Need help with this question Write a Java program that asks the user to enter an array of integers in the main method. The program should prompt the user for the number of elements in the array and then the elements of the array. The program should then call a method named minGap that accepts the array entered by the user as a parameter and returns the minimum 'gap' between adjacent values in the array. The main method should then print the value returned by the method. The gap between two adjacent values in an array is defined as the difference in value between the first element and the second element. For example, suppose the user entered the following array of integers {1, 3, 6, 5, 12} The first gap is 2 (3 - 1), the second gap is 3 (6 - 3), the third gap is 1 (6 - 5) and the fourth gap is 5 (12 - 6). Thus, the call of minGap(array) should return 1 because that is the smallest gap in the array.
