下面是一个示例代码: importjava.io.FileWriter;importjava.io.IOException;publicclassWriteToFile{publicstaticvoidmain(String[]args){Stringcontent="Hello, World!";try{FileWriterwriter=newFileWriter("output.txt");writer.write(content);writer.close();System.out.println("Successfully wrote to the file.");...
首先,我们需要创建一个Java类,例如WriteStringToFile.java,然后编写以下代码: importjava.io.BufferedWriter;importjava.io.FileWriter;importjava.io.IOException;publicclassWriteStringToFile{publicstaticvoidmain(String[]args){Stringcontent="Hello, this is the content to be written to the file.";try(BufferedWri...
8 //Get the file reference Path path = Paths.get("c:/output.txt"); //Use try-with-resource to get auto-closeable writer instance try(BufferedWriter writer = Files.newBufferedWriter(path)) { writer.write("Hello World !!"); } 2.用 Files.write()写入文件 1 2 String content ="Hello Wo...

public class WriteStringToFile { public static void main(String[] args) { try { String aString = "Hello你好"; FileWriter fw = new FileWriter("c:/out.fw.txt"); fw.write(aString); fw.close(); //默认gbk编码9字节 /// OutputStreamWriter osw = new OutputStreamWriter(new FileOutputStream(...
The output in the file will be: We can thenappend aStringto the existing file: The file will then be: 3. Write WithPrintWriter Next, let’s see howwe can usePrintWriterto write formatted text to a file: @TestpublicvoidgivenWritingStringToFile_whenUsingPrintWriter_thenCorrect()throwsIOException...
