如何在其他方法中使用布尔值的return语句？

Question

I have a method that returns true or false,

public boolean confirmVotes()
{
System.out.println("Your vote for President is:" + getVotes() );
System.out.println("your vote for Vice President is:" + getVotes());
System.out.println("Is this correct? Yes or No?");
Scanner keyboard = new Scanner(System.in);
String answer = keyboard.nextLine();
if (answer.equalsIgnoreCase("Yes"))
    return true;
 else 
   return false;
}

How do i use this return statement in another method? This is what i am trying to do

 public void recordVote()
{
        if  comfirmVotes returns true for X
             do this for y

}

Answer 1

If you inspect your confirmVotes method, you will notice that you've already solved this problem:-

if(answer.equalsIgnoreCase("Yes"))

.equalsIgnoreCase(String s) is a method which returns a boolean, and you've already constructed an if statement based on its return value. Thus:-

if (confirmVotes())
{
  // Do whatever
}

Also worthy of note, you can replace:-

if(answer.equalsIgnoreCase("Yes"))
  return true;
else
  return false;

with:-

return answer.equalsIgnoreCase("Yes");

Answer 2

public void recordVote() {
    if (confirmVotes()) { // your method should return true. if it does, it will process the if block, if not you can do stuff on the else block

    } else {

    }
} 

Answer 3

public void myMethod(){
    if(confirmVotes()){
        doStuff();
    }
    else{
        doOtherStuff();
    }
}

Answer 4

I think your problem is how to call a method belong to the same class from a another method of that class. (Because You have already used a return statement of another method inside your first code block.)

You can use this keyword for refering to current instance of the class, or if it is call inside a non-static method, you don't need to use that.

eg:

if (this.confirmVotes() == true)

or (if the calling method is a member method (non-static) or called method is a static method))

if (confirmVotes() == true) {

Because confirmVotes() method returns true, you can also use if(confirmVotes()) instead of comparing it to boolean true again.
