如果你已经在使用Apache Commons Lang库,可以利用StringUtils.stripStart方法来快速去除字符串开头的指定字符(在这个例子中是0)。 java import org.apache.commons.lang3.StringUtils; public class RemoveLeadingZeros { public static void main(String[] args) { String str = "000123"; String result = StringUtils...
37//解决的方法很简单,如果想要避免输出科学计数法的字符串,我们要用toPlainString()函数代替toString()。如:38//System.out.println( new BigDecimal("100.000").stripTrailingZeros().toPlainString());39//此时程序的输出就为 100
StripTrailingZeros() Returns a BigDecimal which is numerically equal to this one but with any trailing zeros removed from the representation. Subtract(BigDecimal, MathContext) Returns a BigDecimal whose value is (this - subtrahend), with rounding according to the context settings. Subtract(BigDecim...

空白字符包括空格,\t,\r,\n: " \tHello\r\n ".trim(); // "Hello" //strip()方法也可以移除字符串首尾空白字符 "\u3000Hello\u3000".strip(); // "Hello" " Hello ".stripLeading(); // "Hello " " Hello ".stripTrailing(); // " Hello" //String还提供了isEmpty()和isBlank()来判断...
