Java large file line by line read example 2023-11-22 01:18
Large file reads are very memory intensive. You can use BufferedReader to read the contents of the file line by line.
public class ReadFile {
public static void main(String[] args) throws Exception {
File file = new File("D:\\testData\\www.csdn.net.sql");
try (BufferedReader br = new BufferedReader(new FileReader(file))) {
String line;
while ((line = br.readLine()) != null) {
System.out.println(line);
}
}
}
}
EOF
