example: JAVA_OPTS='-Xmx512m -XX:MaxPermSize=256m -server -Djava.awt.headless=true'

the problem is (i believe) when the OS gets your string, it breaks your string up into tokens based on the space. You need to tell it that the entire string is the path, and to not break it up. To do that, you need to surround it in quotes. To put quote characters inside a string in java, you need ... |

I don't think it is. Historically, this guy's tactic has been to somehow pretend that the correct solution didn't work, or didn't make sense. Instead, he just said "wow I am dumb".

Always open the API specs for any class that you are using and you are stuck on how to do something using that class. The API specs tell you what methods are already provided for that class which you can use to solve your problems. P.S In this case have a look at the String.replaceAll method. |

Have you tried it. Best way to test it is to compile and run your program. Quicker than typing a reply here and waiting for us to debug your code. Also, if you want to find all the spaces, then you need to do it over and over again. So how can you do something multiple times? |

A call to substring creates a substring that chares the character data with the original string (in this case the whole line), so all of your substrings are still forcing the whole lines to be kept in memory. Calling new String() on the substrings will create a new string that doesn't share the character data, so the char[] will be truncated ... |
