這篇文章主要介紹JAVA文件讀寫例題的實(shí)現(xiàn)方法,文中示例代碼介紹的非常詳細(xì),具有一定的參考價(jià)值,感興趣的小伙伴們一定要看完!
練習(xí)
有這樣的一個(gè)words數(shù)組,數(shù)組中每個(gè)字符串的格式為“詞性:單詞”
String[] words = {"verb:eat","verb:drink","verb:sleep","verb:play","noun:rice","noun:meat","noun:hand","noun:hair"};
根據(jù)單詞性質(zhì)動(dòng)詞verb全部存入verb.txt文件中
根據(jù)單詞性質(zhì)名詞noun全部存入noun.txt文件中
package readandwrite; /*1.有這樣的一個(gè)words數(shù)組,數(shù)組中每個(gè)字符串的格式為“詞性:單詞” String[] words = {"verb:eat","verb:drink","verb:sleep","verb:play","noun:rice","noun:meat","noun:hand","noun:hair"}; 根據(jù)單詞性質(zhì)動(dòng)詞verb全部存入verb.txt文件中 根據(jù)單詞性質(zhì)名詞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數(shù)組 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(); } }
