System.out.println(y); : 0 - What will be the output of the following code?
byte b;
double d = 417.35;
b = (byte) d; System.out.println(b); : 161 - Given the value of a variable, write a statement, without using if construct, which will produce the absolute value of the variable. : x = x<0?-x:x;

case 2:
n3 = 30;
break;
n4 = 40;
} : n4 = 40; is unreachable - What will be the output of the following program code?
