练习

有这样的一个words数组，数组中每个字符串的格式为“词性:单词”

String[] words = {"verb:eat","verb:drink","verb:sleep","verb:play","noun:rice","noun:meat","noun:hand","noun:hair"};

根据单词性质动词verb全部存入verb.txt文件中

根据单词性质名词noun全部存入noun.txt文件中

package readandwrite;/*1.有这样的一个words数组，数组中每个字符串的格式为“词性:单词” String[] words = {"verb:eat","verb:drink","verb:sleep","verb:play","noun:rice","noun:meat","noun:hand","noun:hair"}; 根据单词性质动词verb全部存入verb.txt文件中 根据单词性质名词noun全部存入noun.txt文件中*/import java.io.*;public class FileReadAndWrite { public static void main(String args[]) throws IOException { //WORDS数组 String[] words = {"verb:eat","verb:drink","verb:sleep","verb:play","noun:rice","noun:meat","noun:hand","noun:hair"}; FileOutputStream outFile1 = new FileOutputStream("verb.txt"); FileOutputStream outFile2 = new FileOutputStream("noun.txt"); OutputStream out1 = new BufferedOutputStream(outFile1); OutputStream out2 = new BufferedOutputStream(outFile2); for(int i=0;i<words.length;i++){ if(words[i].startsWith("verb")){ byte[] bytes1 = words[i].getBytes(); out1.write(bytes1); } if(words[i].startsWith("noun")){ byte[] bytes2 = words[i].getBytes(); out2.write(bytes2); } } out1.close(); out2.close(); }}
