[–引自java批量替换文件名指定字符][java]

package rename;
    import java.util.*;
    import java.io.*;
    public class FileOperator{
        public static void main(String[] args)throws IOException{
            String fileStr="";
            String rStr="";
            String newStr="";
            try{
            System.out.print("\n输入文件夹路径：");
        	Scanner fsc = new Scanner(System.in); 
            fileStr = fsc.nextLine();
            System.out.print("\n输入被替换字符：");
            Scanner rsc = new Scanner(System.in); 
            rStr = rsc.nextLine();
            System.out.print("\n输入替换字符：");
            Scanner newsc = new Scanner(System.in); 
            newStr = newsc.nextLine();
            }catch(Exception e){
            	System.out.println("Error: 001--"+e.getMessage());
            }
            RenameFile(fileStr,rStr,newStr);
        }
        public static boolean RenameFile(String filepath,String rStr,String newStr) throws IOException{ 
          try { 
            File fileDir = new File(filepath);
            	for (File file : fileDir.listFiles())
            	{
                    if(file.isFile()){
                        String fileName = file.getName();  
                        String newName = fileName.replace(rStr,newStr);  
                        File f_new = new File(filepath, newName);
                        file.renameTo(f_new);
                        System.out.println(filepath+"\\"+fileName+">>"+filepath+"\\"+newName+"-----"+f_new.exists());
                    }
        		}
        	}catch(Exception e){ 
        	    System.out.println("错误信息: " + e.getMessage()+"   请确认文件夹是否处在！");
        	}
        return true; 
      }
    }
