"possible loss of precision", except not, code doesn't work, simple question

Hello,

I'm trying to make my array as compact as possible. since a calculation will not go above 60, i used byte data type, but the compiler says 'possible loss of precision' and then doesn't run the array. Here is the code fragment:

Code :

---

tarray=new byte[6][10];
		for(byte y=0;y<6;y++){
			for(byte x=0;x<10;x++){
				tarray[y][x]=(y*10)+x;
				System.out.println("tilearray "+y+","+x+": "+tarray[y][x]);
			}
		}

---

The following very similar code has the same error, but outputs the value:

Code :

---

byte six=6;
byte ten=10;
byte mul=six*ten;
System.out.println(mul);

---

So why doesn't my array output the information.

Tell the compiler you know what you are doing by casting the int result to byte:
int var = (byte) (int expression here);

thank you Norm, it's fixed
