Method of converting char array to string: It can be achieved by assignment. Use {char a[]=" abc d\0efg ";string s=a;} syntax to let the char array directly assign a value to string, and execute the code to complete the conversion.

Use java's File.getParent() function to get the parent path of a file. In Java programming, we often need to operate files and folders. Sometimes, we need to get the parent path of a file, which is the path of the folder where the file is located. Java's File class provides the getParent() method to obtain the parent path of a file or folder. The File class is Java's abstract representation of files and folders. It provides a series of methods for operating files and folders. Among them, get

Replace characters (strings) in a string using Java's String.replace() function In Java, strings are immutable objects, which means that once a string object is created, its value cannot be modified. However, you may encounter situations where you need to replace certain characters or strings in a string. At this time, we can use the replace() method in Java's String class to implement string replacement. The replace() method of String class has two types:
