	public static void main(String[] args)
	{
		int three = 3;
		int two = 2;		
		double result = 0;
		
		result = 1.5 + three/two;
		System.out.println("result1=" + result);
		
		result = 1.5 + (double) three/two;
		System.out.println("result2=" + result);
		
		result = 1.5 +  three/(double)two;
		System.out.println("result3=" + result);
