if (b > c)
answer = c;
else
answer = b;
else
if (a > c)
answer = c;
else
answer = a;
Which of the following sets of values for a, b, and c will cause answer to be assigned the value in variable b?If the value of x is 20, what does this expression evaluate in Java?
0 <= x < 30
What is the output of the following piece of code?
int x = 4, y = 3;boolean b = ++x < y++ || ++x < y++; System.out.println(x+","+y+","+b);
