/**
 * Estimates the maximum display width of the coordinate string based on current integer and
 * fractional part lengths.
 *
 * @return maximum display width
 */
private int getStringWidth() {
  FontMetrics fm = label.getFontMetrics(label.getFont());
  char[] c = new char[intLen + decLen + 1];
  Arrays.fill(c, '0');
  String s = String.valueOf(c);
  s = s + ", " + s;
  return fm.stringWidth(s);
}

代码示例来源：origin: youseries/ureport

public static void main(String[] args) {
  FontMetrics fontMetrics=new JLabel().getFontMetrics(new Font("宋体",Font.PLAIN,12));
  String text="我是中国人，我来自China,好吧！top和bottom文档描述地很模糊，其实这里我们可以借鉴一下TextView对文本的绘制，"
      + "TextView在绘制文本的时候总会在文本的最外层留出一些内边距，为什么要这样做？因为TextView在绘制文本的时候考虑到了类似读音符号，"
