Choose the appropriate return type for the getters and setters provided below. class Test{private int value;public setValue(int value){//some code}public getValue(){//some code}}

public class MyClass{private int value;public void setValue(int i){ / code / }// Other methods…}The method setValue assigns the value of i to the instance field value. What could you write for the implementation of setValue?Question 3Answera.value=iandthis.value = i;b.value = i; c.this.value = i;d.value == i;

Given the following set of classes:public class Customer { private String userName; private String password; public Customer(String userName, String password) { this.userName = userName; this.password = password; } public void setPassword(String password) { this.password = password; } public String getPassword() { return password; } public void setUserName(String userName) { this.userName = userName; } public String getUserName() { return userName; }} class CustomerTest { public static void main(String[] args) { Customer testAcct = new Customer("user","pass"); testAcct.setPassword("Java"); System.out.println(testAcct.toString()); }}What does the toString() method need to look like to result in the following output:UserName: userPassword: Javaa.)public String toString() { String state = "UserName: " + userName + "\n"; state += "Password: " + password + "\n"; return state;}b.)public String toString() { String state = "UserName: " + userName + "\n"; state += "Password: " + password + "\n"; return password;}c.)public String toString() { String state = "UserName: " + userName + "\n"; state = "Password: " + password + "\n"; return state;}d.)public String toString() { String state = "username: " + userName + "\n"; state += "password: " + password + "\n"; return state;}
