Writing Mortgage program in Java

[PPaul1]

/*Write a Java program without a graphical user interface that calculates and displays   the mortgage payment amount given the amount of the mortgage, the term of the  mortgage, and the interest rate of the mortgage. In this program, hard code the  amount = $200,000, the term = 30 years, and the interest rate = 5.75%.  Insert comments in the program to document the program   Here what I have so far I need help completing code Thanks*/

Okay, telling us your problem would be useful. Also, please wrap code in the [code] code goes here. [/code] tags.
But I'll bet it is the missing right parentheses in your System.out.println calls.

}
}
}

[You needed a second bracket behind balance and interest in your printout line. ]
