zfc.java

JAVA写的字符串查找！可以快速查出以该字母开头的所有汉字！

public class zfc {
 private String st = "aAa3";
 private int a;
 private int b;
 private int d;
 public void sb(String st){
  for(int i=0;i<st.length();i++)
  {
   char c = st.charAt(i);
   if('A'<=c&&c<='Z')
     {
      a++;
      System.out.print(c);
     }
  else if('a'<=c&&c<='z')
   {
     b++;
     System.out.print(c);
    }
  else d++;
  }
  System.out.print(a);
  System.out.print(b);
  System.out.print(d);
  System.out.print(st.length());
  }
  public static void main(String[] args){
  zfc  t = new zfc();
   t.sb(t.st);
  }
}
