如:文件filePath = "E:\\test\\test.dxf"
1.获取文件名
eg:获取 test.dxf
通过file对象
import java.io.File; public class test { public static void main(String[] args) { String filePath = "E:\\test\\test.dxf"; File tmpFile=new File(filePath); String fileName=tmpFile.getName(); System.out.println(fileName); } }
使用split
public class test { public static void main(String[] args) { String filePath = "E:\\test\\test.dxf"; //带扩展名的文件名 String temp[] = filePath.split("\\\\"); String fileName = temp[temp.length - 1]; System.out.println(fileName); } }
使用substring
public class test { public static void main(String[] args) { String filePath = "E:\\test\\test.dxf"; String fileName = filePath.substring(filePath.lastIndexOf("\\")+1); System.out.println(fileName); } }
2.获取不带扩展名的文件名
eg:获取 test
使用substring
public class test { public static void main(String[] args) { String filePath = "E:\\test\\test.dxf"; String fileName = filePath.substring(filePath.lastIndexOf("\\")+1); String name = fileName.substring(0,fileName.lastIndexOf(".")); System.out.println(name); } }
3.扩展名
eg:获取 dxf
使用substring
public class test { public static void main(String[] args) { String filePath = "E:\\test\\test.dxf"; String fileName = filePath.substring(filePath.lastIndexOf("\\")+1); String name = fileName.substring(filePath.lastIndexOf(".")+1); System.out.println(name); } }
或
public class test { public static void main(String[] args) { String filePath = "E:\\test\\test.dxf"; String fileName = filePath.substring(filePath.lastIndexOf("\\")+1); String[] strArray = fileName.split("\\."); int suffixIndex = strArray.length -1; System.out.println(strArray[suffixIndex]); } }
或
public class test { public static void main(String[] args) { String filePath = "E:\\test\\test.dxf"; String fileName = filePath.substring(filePath.lastIndexOf("\\")+1); System.out.println(fileName); String extension=fileName.substring(fileName.lastIndexOf(".")+1,fileName.length()); System.out.println(extension); } }
