How can I iterate over the ArrayList made up of integers using the while loops in the java programming language?

Using JAVA, write a method that modifies an ArrayList<String>, moving all strings starting with an uppercase letter to the front, without otherwise changing the order of the elements. Write a test program to demonstrate the correct operation of the method.

import java.util.Scanner;import java.util.ArrayList;import java.util.StringTokenizer; public class PlantArrayListExample {    // TODO: Define a printArrayList method that prints an ArrayList of plant (or flower) objects                                                             public static void main(String[] args) {      Scanner scnr = new Scanner(System.in);      String input;      // TODO: Declare an ArrayList called myGarden that can hold object of type plant       // TODO: Declare variables - plantName, plantCost, flowerName, flowerCost, colorOfFlowers, isAnnual            input = scnr.next();      while(!input.equals("-1")){         // TODO: Check if input is a plant or flower         //       Store as a plant object or flower object         //       Add to the ArrayList myGarden               input = scnr.next();      }            // TODO: Call the method printArrayList to print myGarden         }}

Write a program  in c that create a 5-by-6 array. All elements in the array are random integer numbers between 1 and 100. Then, calculate the mean values of each column, and also find the minimums and maximums of each column. Print out the array, mean values, minimums,

Write a Java method that finds the largest element in an array of integer values and returns this largest element

Write Java statements that use a for each loop to cycle through all the elements in an ArrayList of doubles named grades.

We were given the following code to solve a Pentomino puzzle, several methods might need to be added or editted to solve the problem. The program should take in an input of 3 4 5 6 for 3x20 4x15 5x12 6x10 grids. Then output the number of correct solutions for them (respectively its 2, 368, 1010, and 2339) import java.util.ArrayList;import java.util.LinkedList;import java.util.List; public class DLX {    class DataNode {        DataNode L, R, U, D;        ColumnNode C;                public DataNode() {            L = R = U = D = this;        }         public DataNode(ColumnNode c) {            this();            C = c;        }        DataNode linkDown(DataNode node) {            node.D = this.D;            node.D.U = node;            node.U = this;            this.D = node;            return node;        }        DataNode linkRight(DataNode node) {            node.R = this.R;            node.R.L = node;            node.L = this;            this.R = node;            return node;…

Correct my codes in java // Arraysimport java.util.Scanner;public class Assignment1 {public static void main (String args[]){Scanner sc=new Scanner (System.in);System.out.println("Enter mark of student");int n=sc.nextInt();int a[]=new int [n];int i;for(i=0;i<n;i++){System.out.println("Total marks of student in smster");a[i]=sc.nextInt();}int sum=0;for(i=0;i<n;i++){sum=sum+a[i];}System.out.println("Total marks is :");for (i=0;i<n;i++);{System.out.println(a[i]);}System.out.println();}}

In writing a general-purpose sort method in Java, the sort method needs to compareobjects. There are two ways to give the sort method the code to compare objects,implementing the interfaces Comparable and Comparator respectively. Extend Article class toimplement Comparable interface so that the default sorting of the Articles is by its volume

Write and test a Java method clshift() that performs a circular left shift on an array of nintegers.
