To convert negative number to positive number (this is called absolute value), uses Math.abs(). This Math.abs() method is work like this “number = (number < 0 ? -number : number);".
See a complete example :
package com.mkyong;
public class app{
public static void main(String[] args) {
int total = 1 + 1 + 1 + 1 + (-1);
//output 3
System.out.println("Total : " + total);
int total2 = 1 + 1 + 1 + 1 + Math.abs(-1);
//output 5
System.out.println("Total 2 (absolute value) : " + total2);
}
}
Output
Total : 3
Total 2 (absolute value) : 5
In this case, Math.abs(-1) will convert the negative number 1 to positive 1.
tell me a program of negative and positive
time clock like for example calculating employees hours in and out with minutes included and seconds, it should create a negative number, so Math.abs is a really good tool, because it can actually convert the – sign to and absolute value number, plus it saves the programmer time and work.
Literally just had to write a program to determine if Palindrome or not. 7 years later this was helpful.
shut up bro
Class positive
{
void main (int n )
{
if (n>0)
System.out println (n+”is positive “);
else
System.out . println (n+”is negative “);
}
}
