All in One

I'm in the middle of creating a program [Java] with the help of two other pals I got in school. We will actually defend that program within this week. We are required to use four out of the five statements, namely:

• If statement (which includes the Dangling If's and others)
• Arrays (Whether the normal array or the 2D)
• Switch (commonly known as Case)
• Loop (any of the loops)

So array is divided into two which means we have the power to choose which array to use, and that makes it four.

I'll post the code as soon as we are able to merge our codes. Further discussions would be available regarding the program.

Problem 2: Arrays

Based from the previous problem about arrays, here's another thing which is similar to that problem: Create a program that will allow the user to enter ten numbers and sort the numbers in an ascending and descending order. Then, display the highest and the lowest value of the ten numbers given by the user.

import java.io.*;
import java.util.Arrays;

public class Oc13
{
public static void main (String args[]) throws IOException
{

DataInputStream whatever = new DataInputStream (System.in);

int earth[] = new int [10];
int temp;

System.out.println("Enter 10 numbers: ");

for (int i = 0; i< earth.length/2; ++i ) { temp = earth[i]; earth[i] = earth[earth.length - i - 1]; earth[earth.length - i - 1] = temp; } System.out.println("Descending Order: " + Arrays.toString(earth)); System.out.println("Highest is " + earth[0]); // System.out.println("Lowest is " + earth[10]); } }

Problem: Loop

create a program based on the sample output below:

Enter Number: 5

*

**

import java.io.*;
class s31
{
public static void main (String args[]) throws IOException
{
DataInputStream ethel=new DataInputStream (System.in);

int ctr;

System.out.println("Enter number ");
ctr=Integer.parseInt(ethel.readLine());


for(int i = 1; i <=ctr; i++)
{ for(int j = 1; j <=i; j++)
{ System.out.print("*"); }
System.out.println(); } } }

Loops

There are three different kinds of loops: while, for, and do-while loops.

The uses of these loops are almost alike. But, there are some cases that they're different. It only depends on how you use it.

FOR LOOP

• repeats for a specified number of times

Syntax:

for(initialization; comparison ;increment or decrement)

{statements;}

WHILE LOOP

• a loop that repeats until a certain condition is satisfied

Syntax:

while(condition)

{statements;)

DO-WHILE LOOP

• unlike the while loop, the do-while loop tests the condition at the end of the loop

Syntax:

do

{statements;}

while(condition);
