Description

that takes one integer argument, and returns the boolean value <code>true</code> if
the argument is positive, and <code>false</code> otherwise.

Template / Reference solution

public static \[boolean]\ \[isPositive]\(\[int]\ \[x]\) {
\[
return (x > 0);
]\
}

// basic tests
public static void main (String[] args) {
StdOut.println("126 is positive? " + isPositive(126));
StdOut.println("-126 is positive? " + isPositive(-126));
StdOut.println("0 is positive? " + isPositive(0));
StdOut.println("1 or -1 is positive? "
+ (isPositive(-1) || isPositive(1)));
}

Java test suite
See manual

testMain();
test("isPositive", randgen.nextInt(100)+1);
test("isPositive", -randgen.nextInt(100)-1);

C++ test suite
json list of stdin/args tests
e.g. [{"stdin":"hi", "args":["4", "5"]}, {"stdin":"noargs"}]
to just run once with no input use [{}]
