Answer 1

Answer:

Java Program to check if Number is Positive or Negative

In this post, we will write two java programs, first java programs checks whether the specified number is positive or negative. The second program takes the input number (entered by user) and checks whether it is positive or negative and displays the result.

→ If a number is greater than zero then it is a positive number

→ If a number is less than zero then it is a negative number

→ If a number is equal to zero then it is neither negative nor positive.

noExample 1: Program to check whether the given number is positive or negative

In this program we have specified the value of number during declaration and the program checks whether the specified number is positive or negative. To understand this program you should have the basic knowledge of if-else-if statement in Core Java Programming.

Example 2: Check whether the input number(entered by user) is positive or negative

Here we are using Scanner to read the number entered by user and then the program checks and displays the result.
