前言：
如今你们对“怎么用java创建文件”大体比较重视，兄弟们都想要剖析一些“怎么用java创建文件”的相关知识。那么小编在网上收集了一些关于“怎么用java创建文件””的相关文章，希望我们能喜欢，朋友们一起来学习一下吧！1.直接传字符串
public File(String pathname) { if (pathname == null) { throw new NullPointerException(); } this.path = fs.normalize(pathname); this.prefixLength = fs.prefixLength(this.path);}2.字符串分为父路径和子文件名public File(String parent, String child) { if (child == null) { throw new NullPointerException(); } if (parent != null) { if (parent.isEmpty()) { this.path = fs.resolve(fs.getDefaultParent(), fs.normalize(child)); } else { this.path = fs.resolve(fs.normalize(parent), fs.normalize(child)); } } else { this.path = fs.normalize(child); } this.prefixLength = fs.prefixLength(this.path);}3.字符串分为父类对象子以及文件名字public File(File parent, String child) { if (child == null) { throw new NullPointerException(); } if (parent != null) { if (parent.path.isEmpty()) { this.path = fs.resolve(fs.getDefaultParent(), fs.normalize(child)); } else { this.path = fs.resolve(parent.path, fs.normalize(child)); } } else { this.path = fs.normalize(child); } this.prefixLength = fs.prefixLength(this.path); }例子：package com.frank;import java.io.File;import java.io.IOException;public class file { public static void main(String[] args) throws IOException { createFile01(); } public static void createFile01() throws IOException { String fileName="E:\\leichao.txt"; File file1=new File(fileName); file1.createNewFile(); System.out.println("创建文件成功"); } } 版权声明：
