QUESTION
Hi so i am suppose to be making a priority queue implemented Heap in descending order, largest to small, I want to this with exponents. So i fnished my heap and priority queue classes, but now when making my class I get an error saying
xponents.java:66: error: invalid method declaration; return type required
public Exponent(int num, int exponent, int x)
I'm not sure where im going wrong
public class Exponents implements Comparable
{
private int num;
private int exponent;
private int x;
public Exponents(int num, int exponent, int x)
{
this.num = num;
this.exponent = exponent;
this.x = x;
}
public int Answer()
{
int x = Math.pow(num,exponent);
return x;
}
public String toString()
{
String s = ("Exponent: " + exponent + "\n Number: "+ num + "\nYour x is: )" + x);
return s;
}
public int compareTo(Answer e)
{
return this.x - o.x;
}
}
Problem was fixed because of a typo and now im getting more errors, im not really sure what i wrote wrong:
Exponents.java:83: error: cannot find symbol
public int compareTo(Answer e)
^
symbol: class Answer
location: class Exponents
Exponents.java:74: error: incompatible types: possible lossy conversion from double to int
int x = Math.pow(num,exponent);
^
Exponents.java:85: error: cannot find symbol
return this.x - o.x;
^
symbol: variable o
location: class Exponents
3 errors
ANSWER
Answered 2017-Apr-09 at 09:23There's a typo in your constructor. Your class is named Exponents
but in your constructor, it says Exponent
. It becomes an invalid method declaration because it is looking for a return data type since the name of the 'constructor' you created is not the same as the name of the class.
Edit:
- You do not have a class name
Answer
. - You cannot implicitly cast double to int. You can use
Math.pow(num,exponent).intValue()
- You do not have a variable named
o
within the scope of the method or the class.
