So i created a method that basically similar to Math.pow, but using recursion.However, it works fine except it prints the final result twice, how do i get rid of the last repeated number ? here is my method :-
public static int recursion(int base, int degree) {
if (degree > 0) {
base = base * recursion(base, degree - 1);
System.out.println(base);
[code]....
how do i get rid of that last repeated 81 ?
I wrote a code for a "skydiving" program that randomly selects the "maneuvers" to be performed by the skydiver during his skydive. I am almost done with the program. I just need to figure out how to print non repeated maneuvers for each round. Each round may not consist of two of the same maneuvers. The program that I wrote randomly picks the maneuvers but sometimes it still prints out two of the same maneuvers for each round.The following is my code.
import java.util.Scanner;
import java.util.Random;
///v.0
public class Testpart2 {

I have made a program which finds the number of occurrence of the words. It is as follows :
public class B {
public static void main(String[] args) {
Map<String, Integer> mp = new LinkedHashMap<String, Integer>();
String s = "This is me tarun ohri This";
Scanner p = new Scanner(s);
int i = 0;

Output is coming {This=0, is=1, me=1, tarun=1, ohri=1}
So I'm trying to write a program that prints out the "most-repeated integer" in an Array.
For example: if an array contains {1,2,2,3} It would print out 2 as the result.This is what I got so far and according to my knowledge I think I'm correct but for some reason it doesn't work.. Please give me some inputs.
public class MostInt{
public MostInt (){
int[] array = {0};
for(int i = 0;i>array.length;i++){
if(i==i++){
System.out.println(i);

I got this code with mode methods. The results is not exactly what I want.

import java.util.Arrays;
import java.util.List;
import java.util.Random;
import java.util.*;
public class ProcessMarks {
private static final int NMARKS = 125;
[Code] ...
Result (it's repeat number):
*Mode is = 53
*Mode is = 53
*Mode is = 53
*Mode is = 53
*Mode is = 53
*Mode is = 62
*Mode is = 62
*Mode is = 62
*Mode is = 62
*Mode is = 62
*Mode is = 67
*Mode is = 67
*Mode is = 67
*Mode is = 67
*Mode is = 67
*Mode is = 77
*Mode is = 77
*Mode is = 77
*Mode is = 77
*Mode is = 77
*Mode is = 78
*Mode is = 78
*Mode is = 78
*Mode is = 78
*Mode is = 78
*Mode is = 85
*Mode is = 85
*Mode is = 85
*Mode is = 85
*Mode is = 85
Result that i want it to be (number appear only once):
*Mode = 53, 62, 67, 77, 78, 85
or
*Mode is = 53
*Mode is = 62
*Mode is = 67
*Mode is = 77
*Mode is = 78
*Mode is = 85
for example if the given string is: The world is running java technology?
Ans:
T is =2
h is=2
e is=2
w is=1
n= 4
like wise i need out put of the program?

I have to make a program that prompts the user to enter 10 numbers and at the end it prints out the distinct numbers and then the other numbers that weren't repeated...

I have a beginning Java Program I have been working on that creates a number guessing program where the computer guesses a number that the user is thinking of within a certain range. I so far have the program below, but need getting rid of a few kinks/ adding features.
-First, I need to set it up so that the user will be prompted and give a range. It should run and produce something like this:
Welcome to this first-ever mind-guessing program!
Please pick a range (higher than 1 and no larger than 50): 32
You will choose a number between 1 and 32... and I will try to guess it.
With each of my guess, you will tell me whether I am too high (h or H), too low (l or L), match (m or M), or you want to quit (q or Q). My objective is to find the number using as few guesses as possible.
-Second, the game is supposed to give up and restart after failing the five, guesses, but for some reason, after it fails the fifth time, it prompts a fifth guess once again instead, then restarts after- I need to prevent this, so that it should look something like this:
My fourth guess is 17: h
My guess is too high?
My fifth guess is 16: h
*** I am unlucky this round. I give up.
Let's play!
My first guess is 10:
etc..

So I am currently writing my first assignment and have run into problems with my coding. The task was to have someone enter a 5 digit number and in return, I list each number on their respective lines. We also must create an error if a number other than 5 digits was entered. My problem is that when they enter a 1 or 2,3,4,6,7,8 digit number.. the error message occurs along with the rest of the messages (listing the numbers, etc). I want the program to end (or even re-ask to enter the numbers) if they incorrectly enter the data.

I am trying to create a method that prints the square root of a number up to a certain number. It needs to take a single int parameter for example "n" , and then print all of the (positive) even perfect squares less than n, each on a separate line. I want the method to be called something like this:
public void Squares(int n) {

I am 4 weeks into my Intro to Java course and I am having a bit of trouble with my code. I need to make a program that will take a user inputted number, space the numbers out, then add them to a total sum. What I am having a hard time with is when I enter a negative number.

i am trying to store a number of different value cards for a number of players. E.g there can be 2 , 4 or more players and each player can have any number of cards.
I have decided to use an arraylist for cards and tried using an array for players. But after coding and reading some information online, i realised that it is not possible to have an array of arraylist.
1. Write a Java program that randomly generates a five-digit lottery number and prompts the user to enter a five-digit number. Each digit in the number is in the range between 0~9. The program should determine which prize the user wins according to the following rule:
- The user wins the first prize if the user input matches all five digits in the lottery number in exact order.
-The user wins the second prize if the user input matches any four digits in the lottery number in exact positions.
-The user wins the third prize if the user input matches any three digits in the lottery number in its exact position.
-The user wins the fourth prize if the user input matches any two digits in the lottery number in its exact position.
- The user wins the fifth prize if the user input matches any one digit in the lottery number in its exact position.here is my code. I have tried replacing the && statements with || and it always returns either case 1 or case default.
import java.util.Scanner;
import java.util.Random;

static int getPrize(int g1, int g2, int g3, int g4, int g5,

I'm having a hard time with this problem, this is what I have, but I can not use two integers, I have to use one integer and a string...
This is the question:
Write a method called printStrings that accepts a String and a number of repetitions as parameters and prints that String the given number of times. For example, the call:
printStrings("abc", 5);
will print the following output: abcabcabcabcabc
This is what I attempted:
public class printStringsproject {
public static void printStrings(int abc, int number) {
for (int i = 1; i <= number; i++) {
System.out.print("abc");
}
}
public static void main(String[] args) {
printStrings(1, 5);
