Absolute Value of a number
- Program to determine the absolute value of a given number.
Program
import
java.util.Scanner;
public class
Absolute {
private static
Scanner sc;
public static void
main(String[] args) {
int
num;
sc=new
Scanner(System.in);
System.out.print("Enter
the number:");
num=sc.nextInt();
System.out.print("The
absolute value of "+num+" is ");
if(num<0)
{
System.out.println(-1*num);
}
else {
System.out.println(num);
}
}
}
Output
Enter
the number:-67
The absolute
value of -67 is 67

- Program to find the sum of the digits of a given number.
Program
import
java.util.Scanner;
public class
AddInt {
public void
revInt(int num) {
int
j,f=0;
while(num>0)
{
j=num%10;
f=f+j;
num=num/10;
}
System.out.println("Sum
of the digits = "+f);
}
private static
Scanner sc;
public static void
main(String[] args) {
sc=new
Scanner(System.in);
System.out.print("Enter
an integer:");
int
num=sc.nextInt();
AddInt ob=new
AddInt();
ob.revInt(num);
}
}
Output
Enter
an integer:784
Sum
of the digits = 19
