在文件过滤器列表中提供条件和逻辑。如果列表中的所有过滤器均返回true,则返回true。否则,它返回false。
以下是org.apache.commons.io.filefilter.AndFileFilter类的声明-
public class AndFileFilter
extends AbstractFileFilter implements ConditionalFileFilter, Serializable
这是我们需要解析的输入文件-

让我们打印当前目录中的所有文件和目录,然后过滤名称以开头的文件。并以t结尾
IOTester.java
import java.io.File;
import java.io.IOException;
import org.apache.commons.io.filefilter.AndFileFilter;
import org.apache.commons.io.filefilter.PrefixFileFilter;
import org.apache.commons.io.filefilter.WildcardFileFilter;
public class IOTester {
public static void main(String[] args) {
try {
usingAndFileFilter();
} catch(IOException e) {
System.out.println(e.getMessage());
}
}
public static void usingAndFileFilter() throws IOException {
//get the current directory
File currentDirectory = new File(".");
//get names of all files and directory in current directory
String[] files = currentDirectory.list();
System.out.println("All files and Folders.\n");
for( int i = 0; i < files.length; i++ ) {
System.out.println(files[i]);
}
System.out.println("\nFile starting with . and ends with t\n");
String[] filesNames = currentDirectory.list(
new AndFileFilter(new PrefixFileFilter("."), new WildcardFileFilter("*t")));
for( int i = 0; i < filesNames.length; i++ ) {
System.out.println(filesNames[i]);
}
}
}
它将打印以下结果。
All files and Folders.
.classpath
.project
.settings
bin
input.txt
src
File starting with . or ends with t
.project
