Let’s see different ways to convert acer to square yard and square yard to acer.

### Method-1: Java Program to Convert Acer to Square mile and Square mile to Acer By Using Static Input Value

**Approach:**

- Declare user input of acer and square yard value.
- Then convert acer to square yard and square yard to acer by using the formula.
- Print result.

**Program:**

public class Main { public static void main(String args[]) { //value of acer declared double acer = 1; //value of square yard declared double squareyard = 1; //converting square yard to acer value double a = squareyard * 0.000206612; //converting acer to square yard value double sy = acer * 4840; //printing result System.out.println("Value of "+squareyard+" square yard in acer: "+ a); System.out.println("Value of "+acer+" acer in square yard: "+ sy); } }

Output: Value of 1.0 square yard in acer: 2.06612E-4 Value of 1.0 acer in square yard: 4840.0

### Method-2: Java Program to Convert Acer to Square Yard and Square Yard to Acer By Using User Input Value

**Approach:**

- Take user input of acer and square yard value.
- Then convert acer to square yard and square yard to acer by using the formula.
- Print result.

**Program:**

import java.util.*; public class Main { public static void main(String args[]) { //Scanner class object created Scanner sc=new Scanner(System.in); //Taking the value input of double variable acer System.out.println("Enter value of acer: "); double acer = sc.nextDouble(); //Taking the value input of double variable squareyard System.out.println("Enter value of square yard: "); double squareyard = sc.nextDouble(); //converting square yard to acer value double a = squareyard * 0.000206612; //converting acer to square yard value double sy = acer * 4840; //printing result System.out.println("Value of "+squareyard+" square yard in acer: "+ a); System.out.println("Value of "+acer+" acer in square yard: "+ sy); } }

Output: Enter value of acer: 5 Enter value of square yard: 400000 Value of 400000.0 square yard in acer: 82.6448 Value of 5.0 acer in square yard: 24200.0

### Method-3: Java Program to Convert Acer to Square Yard and Square Yard to Acer By Using User Defined Method

**Approach:**

- Take user input of acer and square yard value.
- Call a user defined method by passing acer and square yard value as parameter.
- Inside method convert acer to square yard and vice versa by using the formula.
- Print result.

**Program:**

import java.util.*; public class Main { public static void main(String args[]) { //Scanner class object created Scanner sc=new Scanner(System.in); //Taking the value input of double variable acer System.out.println("Enter value of acer: "); double acer = sc.nextDouble(); //Taking the value input of double variable squareyard System.out.println("Enter value of square yard: "); double squareyard = sc.nextDouble(); //calling user defined method convert() convert(acer, squareyard); } //convert() method to convert acer to square yard and vice versa public static void convert(double acer, double squareyard) { //converting square yard to acer value double a = squareyard * 0.000206612; //converting acer to square yard value double sy = acer * 4840; //printing result System.out.println("Value of "+squareyard+" square yard in acer: "+ a); System.out.println("Value of "+acer+" acer in square yard: "+ sy); } }

Output: Enter value of acer: 5.5 Enter value of square yard: 555555 Value of 555555.0 square yard in acer: 114.78432966 Value of 5.5 acer in square yard: 26620.0
