用java程序在当前目录下创建一个子目录的方法是利用File对象的mkdirs方法。

完整代码如下：

// 获取当前图片的路径

String path = createImages.getAbsolutePath() + "/Images"

//创建文件对象f，根据path路径

File f = new File(path)

//如果当前不是一个目录就进入if

if (!f.isDirectory()) {

boolean success = f.mkdirs()//创建一个目录

if (success) { //成功打印当前的路径

System.out.println("Created path: " + f.getPath())

} else { //失败的情况

System.out.println("Could not create path: " + f.getPath())

}

} else {

System.out.println("Path exists: " + f.getPath())//子目录已存在。

}

关于mkdir：

mkdir（）创建此抽象路径名称指定的目录（及只能创建一级的目录，且需要存在父目录），如果传入的path是多级路径，需要使用mkdirs()创建。
