BufferedReader in = new BufferedReader(new FileReader("foo.in")); will buffer the input from the specified file. Without buffering, each invocation of read() or readLine() could cause bytes to be read from the file, converted into characters, and then returned, which can be very inefficie...
will buffer the input from the specified file. Without buffering, each invocation of read() or readLine() could cause bytes to be read from the file, converted into characters, and then returned, which can be very inefficient. 我的第一个问题是,如果bufferedReader可以读取字节,那么为什么我们不能...
First, we’ll learn how to load a file from the classpath, a URL, or from a JAR file using standard Java classes. Second, we’ll see how to read the content withBufferedReader,Scanner,StreamTokenizer,DataInputStream,SequenceInputStream,andFileChannel. We will also discuss how to read a U...
它使用BufferedReader对象进行读取。 另一种方法可以使用InputStream实现。package com.howtodoinjava.test.nio;import java.io.BufferedReader;import java.io.FileReader;import java.io.IOException;publicclassWithoutNIOExample{publicstaticvoidmain(String[] args){ BufferedReader br = null; String sCurrentLine ...

改进的错误恢复机制是提高代码健壮性的最强有力的方式。错误恢复在我们所编写的每一个程序中都是基本的要素,但是在 Java 中它显得格外重要,因为 Java 的主要目标之一就是创建供他人使用的程序构件。 发现错误的理想时机是在编译期。然而,编译期并不能找出所有错误,余下问题必须在运行时解决。这就需要错误源能通过某...
