# Java Program to add two Fraction

In this post, we will learn how to add two fractions and calculate result in simplified form. Implementation Using Java: import java.util.Scanner;
public class CalFraction {
int num;
int den;
CalFraction(int num, int den)
{
this.num=num;
this.den=den;
}
public static void main(String[] args) {
Scanner sc= new Scanner(System.in);
System.out.println("Enter the num of f1");
int num1=sc.nextInt();
System.out.println("Enter the den of f1");
int den1 =sc.nextInt();
System.out.println("enter the num of f2");
int num2=sc.nextInt();
System.out.println("Enter the den of f2");
int den2=sc.nextInt();
CalFraction f1=new CalFraction(num1,den1);
CalFraction f2=new CalFraction(num2,den2);
}
{
this.num=this.num*f2.den+this.den*f2.num;
this.den=this.den*f2.den;
simplify(this.num,this.den);
}
public void simplify(int num,int den)
{
int gcd=1;
int small=Math.min(num,den);
for(int i=2;i<=small;i++)
{
if((num%i==0) && (den%i==0))
gcd=i;
}
num=num/gcd;
den=den/gcd;
}
} Output:
Enter num of f1 2
Enter den of f1 5
Enter num of f2 2
Enter den of f2 5
