Question

Answer in jave. Do not use print or println, only return. This is a codingbat problem.

Given a number, is it greater than or equal to 20 and less than 30. If it is, return true. If not, return false.


between20And30(100) → false
between20And30(24) → true
between20And30(20) → true

Answer 1

In Java, you can use the comparison operators and logical operators to determine if a number is between 20 and 30.

Step-by-step explanation:

In Java, you can use the comparison operators to determine if a number is greater than or equal to 20 and less than 30. You can achieve this by using the logical operators '&&' (AND) and '>' (greater than) and '<' (less than).

To solve the codingbat problem, you can write a method like this:

public boolean between20And30(int num) {
return num >= 20 && num < 30;
}

The method takes an integer 'num' as input and checks if it satisfies the given condition. If the condition is true, it returns 'true'. Otherwise, it returns 'false'.
