Set int to a blank in array

i want to set my array to print out a blank space when it meets its condition in an IF statement. This array is a int data type. When i type: 

item2[2] = ' ';

it comes up as 32 when i print it.

Any solutions?

If you want to store char in an array, why not use a char[]

char[] item2 = new char[10];
item2[2] = ' '; 
System.out.println('|' + items2[2]+'|');

prints

The character ' ' has that value 32 on int, you need to diference when put a blank or not. If your space of values is for example only positive values, you can save a -1 where do you what a space and your code could be something like this:

for(int i:item2){
  if(i == -1) {
    //Print a blank
  } else {
    //Print the number
  }
}

Or you can do a better way, instead of using int, use an array of class Integer, autoboxing will do the automatic convertion and use null as "blank value"

It's an int array. It can only hold integers.

32 is the ASCII value for space, and that's what's being stored when you say item2[2] = ' ';.

No. as your data type is int it will print int representation.

if you cast to (char) then it might mess up with actual number to char which isn't needed,

and it is coming 32 because ascii value of ' ' is 32

Better to go for array of String it will hold both number as well as space . and process them accordingly

Ascii value of ' ' (space) is 32 in html, thats why it is echoing 32.

So the char ' ' will be converted to int, which is 32
