		} catch (Exception ex) {
			ex.printStackTrace();
		}
	}

	private static int recursionCounter = 0;
	private static int REC_LIMIT = 1000;

	/**
	 * Dont assume that data is available and system will come out smoothly.
	 * without safe check, it may enter into stack overflow.

	 */
	private void checkLogicOneSafe(long i) {
		try {

				return;
			} else
				recursionCounter++;

			checkLogicOneSafe(i + 1);

Question: How to format currency. Example: -1234.34 to -$1,234

import java.text.DecimalFormat;
import java.text.NumberFormat;
import java.util.ArrayList;
import java.util.Locale;

public class CurrencyTest {

	public static void main(String[] test) {
		double currency = -1234;
		NumberFormat dollarFormatter;
		dollarFormatter = NumberFormat.getCurrencyInstance(Locale.US);

		if (dollarFormatter instanceof DecimalFormat) {
			((DecimalFormat) dollarFormatter).setMaximumFractionDigits(0);
			((DecimalFormat) dollarFormatter).setNegativePrefix("-$");
			((DecimalFormat) dollarFormatter).setNegativeSuffix("");
		}

		String text = dollarFormatter.format(currency);
		System.out.println(text);
	}
}

Input: -1234.34
Output: -$1,234
