Type Casting

Key Ideas

• put data type in parentheses before whatever you want to cast
• only "casts" the item immediately next to it
  • double x - (double) 1 + 1 / 2; // 1.0
  • double y = 1 + (double) 1 / 2; // 1.5
• you can use parentheses to escape

Example

class Main {
public static void main(Stringp[ args){
	double x = 4 / 3;
	double y = (double)(125/10);
	double z = (double) 28 / 5;
	System.out.println(x + " " + y + " " + z);
	}
}

Debugging

• You can use "print" statements to get the code to show you what's wrong

• Analyze every single line of code

• Talk to le rubber ducky 🦆 (or any inanimate object)
