1.3 Types — boolean from a comparison

Lesson

A comparison like 3 > 2 produces a boolean — true or false. A boolean holds only these two values (not 1/0).

boolean ready = (3 > 2);
System.out.println(ready);  // true

▶ Try it: run this, then change something and run it again.

boolean b = (10 > 3);
System.out.println(b);
System.out.println(4 <= 3);

What does System.out.println(3 > 2); print?

Check answer

True or false?

Check answer

Type exactly what this prints:

boolean b = (10 > 3);
System.out.println(b);

Check answer

Write the body of isPositive that takes an int n and returns true when n is greater than 0, and false otherwise.

For example, isPositive(5) returns true; isPositive(-2) returns false.
