Consider the following Java-like program fragment. (There are line numbers to the left of each line of code that are not part of the program.) 1 j = 1; 2 y = 1.0; 3 s = false; 4 if (j < y) 5   { j = s; } 6 else 7   { s = y; } 8 y = j; Assume that the Java-like language uses dynamic typing and is strongly-typed. Widening conversions are allowed, but narrowing conversions are not. Which lines produce type errors?
