Java methods for distinguishing between absolute and relative paths _java

This article illustrates the Java method for distinguishing between absolute and relative paths. Share to everyone for your reference. The specific analysis is as follows:

Here is the directory path to distinguish

Such as:

/opt/deve/tomcat/bin
C:\deve\tomcat\bin
are all absolute directory paths

Bin
Bin/data
Bin\data
are relative directory paths

By observing and discovering the law

To/start or include \ or//are absolute paths or
At/start or include: absolute path
The opposite is the relative path.

Introduce several methods:

StartsWith public
class Stringutil {public
 static void Main (string[] args) {
  String path = '/opt/bin ';
  System.out.println (Path.startswith ("/"));
 }

Result: True
IndexOf

Final Result:

/**
 * Incoming path, returns whether is absolute path, is absolute path returns true, vice versa
 * 
 @param path
 * @return
 * @since April 21, 2015
 * * Public
boolean Isabsolutepath (String path) {
 if (Path.startswith ("/") | | path.indexof (":") > 0) {
  return true;
 }
 return false;
}
