Question

Method createNewArray that accepts one integer parameter for sizing the integer array the method will return. The method will create a new integer array of the size specified by the parameter, fill it with random values from 1 thru 100 (inclusive) and return the new array.

Answer 1

Program:

import java.util.*;

class CreateArray
{
public static int[] createNewArray(int size)
{
int newArray[]=new int[size];
Random ran=new Random();
for(int i=0;i<size;i++)
{
newArray[i]=(int)(Math.random()*(100-1)+1); //(int)(Math.random()*(upper-lower)+lower)
}
return newArray;
}

public static void main(String args[])
{
Scanner input=new Scanner(System.in);
System.out.print("\nEnter the size of the array: ");
int size=input.nextInt();

int newArray[]=new int[size];

newArray=createNewArray(size);

System.out.println("\nArray elements :\n");
for(int i=0;i<size;i++)
{
System.out.print(newArray[i]+"\t");
}
System.out.println("\n");
}
}

Output:
