How to print an array elements in a single line in java?

Answer 1

By single line I assume you want something that's already been made for you.

Then you can use toString in the Arrays class:

int[] ex = {3,2,1};
System.out.println(Arrays.toString(ex));

It's pretty much the same thing Rishci said, but probably without concatenation. (They likely used StringBuilder)

Answer 2

use System.out.print() instead of System.out.println()

//example
class ABC
{
public static void main(String args[])
{
int a[]={1,2,3,4,5};
int l=a.length;//finds the length of the array
for(int i=0;i<l;i++)
System.out.print(a[i]+" ");
}
}

Answer 3

Add each element to a string using +=.
