我正在使用 JDK 8 在 MacOS 上工作。我想計算給定字符串中特殊字符的數量，但在給定代碼中，特殊字符被計為空格。我應該怎么辦？public static void main(String args[]){ String str; int lc=0,uc=0,d=0,s=0,spc=0; Scanner sc=new Scanner(System.in); System.out.print("Enter the string:"); str=sc.nextLine(); for(int i=0;i<str.length();i++)   {    if(str.charAt(i)>='a' && str.charAt(i)<='z')    {    lc++;    }    else if(str.charAt(i)>='A' && str.charAt(i)<='Z')    {    uc++;    }    else if(str.charAt(i)>='0' && str.charAt(i)<='9')    {    d++;    }    else if(str.charAt(i)>=32)    {    s++;    }    else if(str.charAt(i)>=33 && str.charAt(i)<=47 || str.charAt(i)==64)    {    spc++;    }   }System.out.println("number of small characters in "+str+" are:"+lc);System.out.println("number of CAPITAL characters in "+str+" are:"+uc);System.out.println("number of digits in "+str+" are:"+d);System.out.println("number of Spaces in "+str+" are:"+s);System.out.println("number of Special characters in "+str+" are:"+spc);}這是我得到的輸出：Enter the string:abc23@#$% number of small characters in abc23@#$% are:3number of CAPITAL characters in abc23@#$% are:0number of digits in abc23@#$% are:2number of Spaces in abc23@#$% are:4number of Special characters in abc23@#$% are:0它應該顯示 4 個特殊字符而不是 4 個空格。
