Integral calculator
Topic in English ----
This program is for class 8. In this Java program, we will add two numbers and subtract two numbers,To add two numbers, use the + sign and to subtract two numbers, use the - sign. In this program we have used IF and ELSE
In this program we will check the string whether it is equal to plus sign or minus sign number.If the number is not plus sign and not minus sign then it will go to execution else part which will give you wrong input.To check a string in a Java program the .equals keyword is used.
We use that to check the condition if the condition is true, then the if part returns the value.If part not true,hence else part is true.
Building an Integral Calculator in Java for Addition and Subtraction
where mathematics and logic converge, lies the art of crafting tools that perform complex calculations effortlessly. Today, we embark on a journey to create an integral calculator in Java, a versatile language that empowers us to perform addition and subtraction operations with precision. Join us as we delve into the intricacies of code, witnessing the birth of an integral calculator that responds to the touch of '+' and '-' signs.
## The Allure of an Integral Calculator
Source code of Program
import java.util.*;
class add //Class name
{
public static void main(String args[])
{
Scanner ob=new Scanner (System.in);
System.out.println("Add to + sub to -");
String j= ob.next(); //input by user
String p="+";
String q="-";
if(j.equals(p))
{
System.out.println("enter two numbers");
int a= ob.nextInt();
int b= ob.nextInt();
System.out.println(""+a+"+"+b+"="+(a+b));
}
else if(j.equals(q))
{
System.out.println("enter two numbers");
int a= ob.nextInt();
int b= ob.nextInt();
System.out.println(""+a+"-"+b+"="+(a-b));
}
else
{
System.out.println("Wrong input sign");
}
}
}
integral calculator is a powerful tool that simplifies mathematical calculations by allowing users to perform a variety of operations, such as addition and subtraction,with just a few keystrokes. Such tools find applications in various fields.
