why does (short) 150,000 print 18,928

I solved the task, but I'm not sure how casting 150,000 as a short turns the number into 18,928.

150_000 is an int and in binary notation: 000000_00000010_01001001_11110000 If you cast that to a short, then this means you cut off the first two bytes and that results in: 01001001_11110000 and that again is the value 18_928

int value1 = 0b000000_00000010_01001001_11110000;
int value2 = 0b01001001_11110000;
System.out.println(value1);
System.out.println(value2);
System.out.println(Integer.toBinaryString ((short) value1));
