与同一范围内的代码行嵌套 IF 条件

Question

// TRYING TO PUSH ELEMENT IN STACK WHILE APPENDING THE STRINGBUILDER

if(s.charAt(i)=='('){
                if(bracket.size()>0){
                    sb.append(s.charAt(i));
                }
                  bracket.push(s.charAt(i));
                     // why this line of code is getting executed when size is greater than 1
                 }

if(s.charAt(i)=='('){
                if(bracket.size()>0){
                  sb.append(s.charAt(i));
                }
                 bracket.push(s.charAt(i)); 

                 //this line of code should not execute when bracket size is greater than 1.
                 }

当满足 if 条件时，不应执行将元素推入堆栈的名为括号的行。

Answer 1

设置大于0就执行
