Question

Java arrays

Create method named repeatedN that takes two integer parameters named range and n and returns an integer array

Method should return an integer array that has numbers 0 - range repeated in order n times

If range is less than or equal to 0; return an array that has 0 repeated n times

Create a second method named printArray that takes an integer array as a parameter. The method should print out every element on the same line separated by spaces and place the cursor on the next line after printing all the elements

example:

int[] a = repeatedN(4, 2);     {0, 1, 2, 3, 4, 0, 1, 2, 3, 4}

int[] a2 = repeatedN(0, 3);   {0, 0, 0}

Answer 1

check out the solution and let me know if any queries through COMMENTS.

--------------------------------------------------------------------------

public class MyClass {
// main method
public static void main(String args[]) {
// method call and save the returned array
int[] a = repeatedN(4, 2);
// method call with returned array
printArray(a);
  
// remove comments for the below 2 lines for another method call
//int[] a2 = repeatedN(0, 3);
//printArray(a2);
  
} // main method ends
  
// method which returns integer array
public static int[] repeatedN(int range, int n) {
// finding size of array
int size = (range+1)*n;
// declare an array with required size
int[] arr = new int[size];
// initialize the index of newly created array
int k=0;
  
// if range <= 0 then array contains 0 in n times
if(range <= 0) {
for(int i=0; i<n; i++) {
arr[i] = 0;
}
}
// if range > 0 then array contains from 0-range in n times
else {
for(int i=0; i<n; i++) {
for(int j=0; j<=range; j++) {
arr[k] = j;
k++;
}
}
}
// return array
return arr;
  
} // method ends
  
// method which prints returned integer array
public static void printArray(int[] repeatedArray) {
// print the array in same line with spaces in between
for(int i=0; i<repeatedArray.length; i++) {
System.out.print(repeatedArray[i] + "\t");
}
// place the cursor in next line
System.out.println();
} // method ends
  
} // class ends
