In the previous article we have discussed Java Program to Compute (a/b)x where Value of a, b and x are Given
In this program we are going to see how to compute (a+b)2+(a-b)2 where value of a and b are given by using Java programming language.
Some of the example to how to compute the values of a and b are:
- A B Java
- A^B In Java
- Java A B
- A B In Java
- Java Ab
- (A+B)^2-(A-B)^2
- A 2 B 2 Formula
- (A-B)(A+B)
- A & B In Java
- A%B In Java
- A-B 2
- (A +B)^2
- (A-B)2
- A%B Java
- A^B Java
- (A+B)2-(A-B)2
- (A+B)^2+(A-B)^2
- (A+B)2 + (A-B)2
- A+B)^2+(A-B)^2
- (A+B)2+(A-B)2
- (A+B)^2 + (A-B)^2
Java Program to Compute (a+b)2+(a-b)2 where Value of a and b are Given
The formula of (a+b)2+(a-b)2 is given below.
(a+b)2+(a-b)2 = 2(a2 + b2)
Now we will convert this into a valid Java expression.
Let x= (a+b)2+(a-b)2
= 2(a2 + b2)
= 2*((a*a) + (b*b))
Example:
Suppose a=2 and b=2, Then (a+b)2+(a-b)2 = 2*((a*a) + (b*b)) =2*((2*2)+(2*2)) =16
Now let’s see different ways to compute (a+b)2+(a-b)2
- By Using Static Input Value
- By Using User Input Value and Pow() Function
- By Using User Defined Method
Method-1: Java Program to Compute (a+b)2+(a-b)2 where Value of a and b are Given By Using Static Input Value
Approach:
- Declare and initialize two integer variables say
a
andb
. - By using the formula compute (a+b)2+(a-b)2
- Print the result.
Program:
class Main { public static void main(String[] args) { //declare the first integer variable with a integer value int a= 4; System.out.println("a= " +a); //declare the second integer variable with a integer value int b= 2; System.out.println("b= "+b); //declare another integer variable and assigned the formulated value to it. int c= 2*((a*a) + (b*b)); System.out.println("(a+b)2+(a-b)2 = "+c); } }
Output: a= 4 b= 2 (a+b)2+(a-b)2 = 40
Method-2: Java Program to Compute (a+b)2+(a-b)2 where Value of a and b are Given By Using User Defined Method and Pow() Function
Approach:
- Declare two integer variables say
a
andb
. - Prompt the user to enter the values to the corresponding variables by using Scanner class.
- Then By using the formula compute (a+b)2+(a-b)2
- Print the result.
Program:
import java.lang.Math; import java.util.Scanner; class Main { public static void main(String[] args) { //create object of scanner class. Scanner sc=new Scanner(System.in); System.out.print("a= "); //Take the first input from the user. int a= sc.nextInt(); System.out.print("b= "); //Take the second input from the user. int b= sc.nextInt(); //declare another double variable and assigned the formulated value to it. double c=2*(Math.pow(a,2)+ Math.pow(b,2)); //Typecasting the value of c to integer value System.out.println("(a+b)2+(a-b)2= "+(int)c); } }
Output: a= 4 b= 5 (a+b)2+(a-b)2= 82
Method-3: Java Program to Compute (a+b)2+(a-b)2 where Value of a and b are Given By Using User Defined Method
Approach:
- Declare two integer variables say
a
andb
. - Prompt the user to enter the values to the corresponding variables by using Scanner class.
- Then call a user defined method say
computeValue()
and passa
andb
as parameter. - Then inside method by using the formula compute (a+b)2+(a-b)2
- Print the result.
Program:
import java.util.Scanner; class Main { public static void main(String[] args) { //create object of scanner class. Scanner sc=new Scanner(System.in); System.out.print("a= "); //Take the first input from the user. int a= sc.nextInt(); System.out.print("b= "); //Take the second input from the user. int b= sc.nextInt(); //call the function computeValue(a,b); } //define the method public static void computeValue(int a, int b) { //declare another integer variable and assigned the formulated value to it. int c= 2*((a*a) + (b*b)); System.out.println("(a+b)2+(a-b)2 = "+c); } }
Output: a= 10 b= 20 (a+b)2+(a-b)2 = 1000
