Here we are explaining how to write a java program to find the sum of two integer numbers So first we have to declare the class AdditionOfTwoNumbers with a public modifier. The name of the class should start with a capital letter. And we can set the modifier as public, private, or protected. An Example of a class declaration is shown below.
public class TestClass
{
}
Here the name of the class is TestClass and the modifier is public.
First, we declare the class AdditionOfTwoNumbers then we open the main() function. Then we declare number1,number2, result as datatype integer. Then we set number1=10 and number2=20. Then we perform the addition by adding number1 and number2 into the variable result. Now the value of the result becomes 30. Then we can display the sum of two numbers as the value of the result using system.out.println
.
STEP 1: Declare the class AdditionOfTwoNumbers with a public modifier
STEP 2: Open the main() to start the program, Java program execution starts with the main()
STEP 3: Declare the variables number1,number2,result as integer.
STEP 4: Assign number1=10,number=20.
STEP 5: Calculate the result as number1+number2
STEP 6: Display the result using system.out.println
.
public class AdditionOfTwoNumbers {
public static void main(String[] args) {
int number1=10,number2=20,result;//Declare the variables
result=number1+number2;//Calculate the sum
System.out.println("Sum of two integer numbers: "+result);//Display the result
}
}
Sum of two integer numbers: 30
