问题
The first line using the && operator is giving me an error that says "Illegal start of expression."
第一行使用&&运算符时出现错误，错误信息为“表达式的起始无效”。
英文:
if (valid(num1,base)) && (valid(num2,base)){while(num1>0 || num2>0){String d1 = extractDigit(num1);String d2 = extractDigit(num2);num1 = removeDigit(num1);num2 = removeDigit(num2);String d3 = d1 + d2;if (d3 >= Integer.parseInt(base)){carry = d3/Integer.parseInt(base);d3 = d3 % Integer.parseInt(base);}else{carry = 0;}ans = makeAns(ans, idx, d3);idx = idx + 1;}if (carry > 0){ans = makeAns(ans,idx,carry);}return ans;}else{return "Invalid input";}

你在那一行中有太多的括号。
应该是
整个if语句需要在条件周围加上括号，就像你在其他if和while语句中所做的那样。
英文:
You have too many parentheses in that line.
if (valid(num1,base)) && (valid(num2,base)){
should be
if (valid(num1,base) && valid(num2,base)){
The entire if statement requires parens around the conditional, like you've done in your other if & while statements
