根据 Java 中的布尔值打印特定字符串

Question

I m defining a Shape class with constructors, get and set methods, toString methods etc... And in toString method, I have to print " is Filled " or " is not Filled " according to a given boolean value.

I also wrote a getter method for boolean type such as:

    ...
    ...
    private boolean filled;
    ...
    ...

    //Constructor 
    public Shape(boolean f){
        filled = f;
    }
    ...

    // Getter Method for Boolean values
    public boolean isFilled(){
        return filled;
    }

But I have no idea how to write a proper toString method which prints out "is filled " or " is not filled " according to a given value of " boolean filled "

any help? thanks in advance

Answer 1

You can use the ternary operator to achieve what you want

Solution

boolean filled;
// code
@Override
public String toString(){
    return "blabla " + (filled? "filled" : "not filled") + " other blabla";
}

Answer 2

You can do it like following:

public String toString()
{
    if(isFilled())
    {
        return "is filled";
    }
    else
    {
        return "is not filled ";
    }
}

Answer 3

How about :

public String toString() {
    return filled ? "is filled" : "is not filled";
}
