如何使用java.text.MessageFormat格式化小数百分比

import java.text.MessageFormat;
import java.text.NumberFormat;
import java.util.Locale;

public static String formatPercentage(double value) {
    NumberFormat percentFormat = NumberFormat.getPercentInstance(Locale.getDefault());
    percentFormat.setMinimumFractionDigits(2);
    percentFormat.setMaximumFractionDigits(2);
    return percentFormat.format(value);
}

public static void main(String[] args) {
    double percentage = 0.2345;
    String formattedPercentage = formatPercentage(percentage);
    String message = MessageFormat.format("The percentage is {0}", formattedPercentage);
    System.out.println(message);
}

The percentage is 23.45%
