End of file while parsing

Question about the task

Under discussion

error:reached end of file while parsing. How can i solve this?

The public static toOctal(int) method must convert the integer received as an input parameter from the decimal numeral system into octal. And conversely, the public static toDecimal(int) method converts from the octal system into decimal.
The methods only work with positive numbers. If the input parameter is less than or equal to 0, the methods return 0.
Your task is to implement these methods.

One algorithm for converting a decimal number to octal is as follows:

i is equal to 0
while (the decimal number is not 0) {
the octal number = the octal number + (remainder of the division of the decimal number by 8) * 10 to the power of i
the decimal number = the decimal number / 8
increase i by 1
}

One algorithm for converting an octal number to decimal is as follows:

i is equal to 0
while (the octal number is not 0) {
the decimal number = the decimal number + (remainder of the division of the octal number by 10) * 8 to the power of i
the octal number = the octal number / 10
increase i by 1
}

The main() method is not involved in testing.

Hint: You can use the Math.pow(number, degree) method to raise a number to a power.

Requirements:

The toOctal(int) method needs to be implemented as outlined in the task conditions.
The toDecimal(int) method needs to be implemented as outlined in the task conditions.
The Integer.toOctalString(int) and Long.toOctalString(int) methods cannot be used.
The Integer.parseInt(String, int) and Long.parseLong(String, int) methods cannot be used.
The Integer.toString(int, int) and Long.toString(long, int) methods cannot be used.
You cannot use a BigInteger object.
You cannot use a BigDecimal object.

Make sure to have a counter part for each opening parenthesis/ curly bracket (lines 31 - 34). Another problem will be that you rely on implicit type casting from double to int. Instead you need to use explicit casting using (int).
