You can try this

I need a regex for patterns like
1) {-1,},
2) {-1,-2},
3) {,-2}
Please help me out.
try this,
String regex="\\{-?(\\d+)?,-?(\\d+)?},?";
String str="{-2,}";
System.out.println(str.matches(regex));
Try this,
^\{(\-\d+)?,(\-\d+)?\}$
Hope it works for you.

How would I check in java if a string entered match the required format of aa/dddd where a represents a lower or upper-case letter and d represents a number
A simple regex to use: ^[A-Za-z]{2}/[0-9]{4}$
String regex = "^[A-Za-z]{2}/[0-9]{4}$";
String test = "ab/1232";
if (test.matches(regex)) {
// my regex matches
}
try this,
String str="aF/1234";
if(str.matches("[a-zA-Z]{2}/\\d{4}"))
System.out.println("Match");
I believe
String.matches("[A-Za-z]{2}/\\d{4}")
or
String.matches("[A-Za-z]{2}/[0-9]{4}")
would work.

I'm having some problems with understanding how regular expressions work.
I am using Autolocation with Tasker on my android and have marked 2 types of locations with the patterns
[Safe] theNameOfTheSafePlace
and
[Danger] theNameOfTheDanger
I am trying to find out if the area I'm in is marked as safe or dangerous. I have tried using regex with the name
/[Safe/](.+)
but it doesn't recognize it.
What am I doing wrong and what would be the correct way to write this expression?
Thanks
You should be using backslashes \ to escape the [] not forward slashes.
Try:
\[safe\](.+)
Should be "\[Safe\](.+)" instead of "/[Safe/](.+)" ?

I got a question states that, "we will give you a string ex:Most of the people are living in apartments and they are rich too. In this given string we have to remove "are" and we have to display the rest things...
I don't know what to do???
By simply using : "Most of the people are living in apartments and they are rich too".replaceAll("are","");
see the documentation
http://docs.oracle.com/javase/7/docs/api/java/lang/String.html#replaceAll(java.lang.String, java.lang.String)
use
"Most of the people are living in apartments and they are rich too".replaceAll("are","")

I have a question about how to write a regex expression to get the key and value pairs from below string?
{"ReturnCode":"0","ErrorMsg":"success","EncryToken":"##xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"}
Could someone help me learn on what this can be done?
Thanks very much.
This one should suit your needs:
"([^"]+)"\s*:\s*"([^"]+)"
The key is in the first group, the value in the second one.
