using java (Shuffle ArrayList) Write the following method that shuffles an ArrayList of numbers: public static void shuffle(ArrayList list)

What am I doing wrong? JAVA

Given an array with values 5, 10, 15, 20, 25, what are the fewest number of swaps needed to reverse the list?     a.   2     b.   3     c.   4     d.   5   JAVA

I need this program in java please. #Given Arrayarray=[1,1,1,2,2,2,2,2,4,5,5,6,6,6] #Insert valuevalue=3 index=0for x in array:    if value<x:        #inserting to the array in the position index        array.insert(index,value)        print ("Output :",array)        break        #Incrementing position by 1    index=index+1

Java

Complete the combinations function to generate all combinations of the characters in the string s with length k recursively

For JAVA.

public class ArraySection {     static void arraySection(int a[], int b[]) {        int k =  0;        int [] c = new int[a.length];        for(int i = 0; i < a.length; i++) {            for(int j = 0; j < b.length; j++)                if(a[i] == b[j])                    c[k++] = a[i];                                        }        for(int i = 0; i < k; i++)            System.out.println(c[i]);            System.out.println();    }    public static void main(String[] args) {         int a[] = { 1, 2, 3, 4, 5 };        int b[] = { 0, 2, 4,5 };                        arraySection(a,b);        }}   Calculate the algorithm step number and algorithm time complexity of the above program?

Please help with this java problem

Check if Array Elements are Consecutive in Java. Given an array, we need to check if array contains consecutive elements. For example: Input: array[] = {5, 3, 4, 1, 2} Output: true As array contains consecutive elements from 1 to 5 Input: array[] = {47, 43, 45, 44, 46} Output: true As array contains consecutive elements from 43 to 47 Input: array[] = {6, 7, 5, 6} Output: false As array does not contain consecutive elements.
