Java输入流Scanner/BufferedReader使用方法示例

1.使用scanner

使用时需要引入包import java.util.scanner;首先定义scanner对象

scanner sc = new scanner(system.in);
如果要输入整数，则 int n = sc.nextint();
string类型的，则string temp = sc.next();

比如：

import java.util.scanner;

public class test {
    @suppresswarnings("resource")
    public static void main(string[] args) {
        scanner scanner = new scanner(system.in);
        system.out.println(scanner.next());
    }
}

2.使用bufferedreader

用前需要引入 import java.io.reader;

bufferedreader br = new bufferedreader( new inputstreamreader(system.in) );
string input = br.readline();

比如：

import java.io.*;

public class test {

    public static void main(string[] args) {
        try {
            bufferedreader br = new bufferedreader(new inputstreamreader(
                    system.in));
            system.out.println(br.readline());
        } catch (ioexception e) {

        }
    }
}
