In Java, to check if a given number is positive or negative or 0 we can use conditional statements such as if-else or switch statement. For example, if input number is -5, then the resulting output should be “-5 is a negative number”. In this article, we will learn through an example, detailed logic and program explanation for better understanding.

Approach 2: Using Relational operator we can check whether an integer is positive or negative. If number>0 then the number is positive. If number<0 then the number is negative. If a number is neither positive nor negative, the number is equal to 0. Below is the java implementation of the above approach: Approach 3: Using Integer.signum () Method

In the above program, it is quite clear how the variable number is checked to be positive or negative, by comparing it to 0. If you're not sure, here is the breakdown: If a number is greater than zero, it is a positive number. If a number is less than zero, it is a negative number. If a number equals to zero, it is zero.

If a number is greater than zero, it is a positive number. If a number is less than zero, it is a negative number. If a number equals to zero, it is zero.
