Write a program that can check whether two int arrays are identical. Your program (main) should implement and have a call to the following method signature: .1 boolean checkIntArrayEquality(int array1[], int array2[]). What is the time complexity of this program in terms of Big O (write the solution with a thorough explanation .as a comment in your source file) Write a program that takes an int matrix of any size and replaces any zeros in it with a number denoting how many zeroes have been seen. E.g. 1, in place of the first .2 zero; 2 in place of the second zero; 3 in place of the third and so on and so forth. Your program (main) should have a call to the following method signature: void matrixzeroCounter(int array1[][]). What is the time complexity of this program in terms of Big O (write the solution with a thorough explanation as a comment in your :source file). Hint: for a 2D array called arr row_Count = arr.length column_Count =arr[0]. length Create a program that implements a Student class with the properties: XNumber, name, GPA, major. Use this class to create 1) an array of 5 students and 2) an array .3 list of 5 students. Write two methods to calculate the average GPA using an array and array list as argument. Your program (main) should have calls to the method double averegeGPAarray(Student[] array) and double averageGPAlist(ArrayList list)
