Hi Friend,

Try the following code:

public class RandomNumberArray {

private static void showNumbers() {
int randomNumbers=0;
int min = -5;
int max = 45;
int counter=0;
String st="";
int sum=0;
int[] ranNum = new int[50];

for ( int i = 0; i < ranNum.length; i++) {
counter++;
ranNum[i] = (int)(Math.random() * (max - min + 1) ) + min;
randomNumbers=ranNum[i];
st=Integer.toString(randomNumbers);
sum+=ranNum[i];

if(counter==10){
st+="\n";
}
if(counter==20){
st+="\n";
}
if(counter==30){
st+="\n";
}
if(counter==40){
st+="\n";
}
System.out.print(st+" ");
}
int average=sum/50;
System.out.println("\n"+"Average of Numbers is: "+average);
}



public static void main(String[] args) {
showNumbers();
}

}
Thanks
