IN JAVAWrite a method that accepts two integer parameters rows and cols. The output isa comma-separated grid of numbers displayed in column-major order, meaningthe numbers shown increase sequentially down each column and wrap to the topof the next column to the right once the bottom of the current column is reached.ExamplesprintGrid (3, 6) →1, 4, 7, 10, 13, 162, 5, 8, 11, 14, 173, 6, 9, 12, 15, 18printGrid (5, 3) →1, 6, 112, 7, 123, 8, 134, 9, 145, 10, 1511(Ctrl)11

In intellij Create a method which takes two int parameters and swaps them. Print the values before and after swapping. (Example: ‘before swap: x = 5, y = 10; after swap: x=10, y=5).
Write a program called Range_array.java that has a method with one integer array and two integers position1 and position2 as parameters, where 0<=position1<=position2<=a.length-1. The method should construct and return an array that is identical to the given array, but with the values in position1 through position2 deleted. The output should look exactly like what is pictured below please. The code must be editable, and all variables defined within please.
Write a complete Java program named Transpose that contains the following: The main method asks the user to provide n - the number of rows and m – the number of columns for a rectangular matrix of integers from 2 to 10. The main method calls the matrixSetUp() method which creates a rectangular matrix of specified dimensions and populates it with random integers from 0 to 99. Hint: You can use Math.random() to generate random numbers. The main method prints the matrix created by the matrixSetUp () method in the form of a matrix. Hint: in order to print the array in the example format, you can use Arrays.toString(matrix[row]) to print each row. The main method calls the matrixTranspose() method that creates and returns a transpose of the initial matrix. Hint: matrix transpose means: ��[��][��]=�[��][��] The main method prints the transpose of the matrix.
Write a method that takes a RegularPolygon as a parameter, sets its number of sides to a random integer between 10 and 20 inclusive, and sets its side length to a random decimal number greater than or equal to 5 and less than 12. Use Math.random() to generate random numbers. This method must be called randomize() and it must take an RegularPolygon parameter. You can call your method in the program's main method so you can test whether it works, but you must remove or comment out the main method before checking your code for a score. You will also need to make sure you do not remove the import statement "import testing.Math" as this is required to check your code for a score.
java a. A method named contains exists that takes an array of Strings and a single String, in that order, as arguments and returns a boolean value that is true if the array contains the given String. Assume that an array of Strings named names is already declared and initialized. Call the method to see if the array contains the name "Fred", and save the result in a new variable named fredIsHere. b. Given a method named printMessage that takes a String argument and returns nothing, call the method to print out "I love Java!".
