String percentage = "10%";
BigDecimal d ; // I want to get 0.1
采纳答案by Eng.Fouad
BigDecimal d = new BigDecimal(percentage.trim().replace("%", "")).divide(BigDecimal.valueOf(100));

As long as you know that the %symbol will always be at the end of your String:
只要您知道该%符号将始终位于您的 末尾String：
BigDecimal d = new BigDecimal(percentage.substring(0, percentage.length()-1));
d.divide(100); // '%' means 'per hundred', so divide by 100
If you don't know that the %symbol will be there:
如果您不知道该%符号将在那里：
percentage = percentage.replaceAll("%", ""); // Check for the '%' symbol and delete it.
BigDecimal d = new BigDecimal(percentage.substring(0, percentage.length()-1));
d.divide(new BigDecimal(100));

Try new DecimalFormat("0.0#%").parse(percentage)
尝试 new DecimalFormat("0.0#%").parse(percentage)
