java执行字符串中的运算公式

public class runString {        static ScriptEngine jse = new ScriptEngineManager().getEngineByName("JavaScript");        public static void main(String[] args) {          String strs = "1+1*2+(10-(2*(5-3)*(2-1))-4)+10/(5-0)";          try {              System.out.println(jse.eval(strs));          } catch (Exception t) {          }      }  }  

个人修改

public StringfinalResult (String original) {try {  Object temp = jse.eval(original);                String result =temp.toString();                return result;} catch (Exception t) {              return null;}}
