I have one variable which contains integer values in string format as given below:
strValue = "123"
I want to convert this string value to integer type so it will be helpful for mathematical operation.
How can I do that in Javascript(Rhino) Language?
You can use the parseInt function that recieves a string and returns int.
Example:
var string = "123"
var number = parseInt(string)
print(number * 2)

I'm looking for a way to beautifully extract 'user id' from string in Groovy. Lets say I have string "key::${userId}" For example:
String s = "key::123456"
I can extract userId in java style as following
Long.parseLong(s.substring(s.indexOf("::") + 2))
But I believe that there is a way to make it shorter and more neatly
If key:: is always the prefix, you can use the - operator, combined with the as keyword for the String to long conversion:
String s = 'key::123456'
long userId = (s - 'key::') as long
You can use multiple assignment operator combined with tokenize method:
def (_,userId) = "key::123456".tokenize("::")
assert userId == "123456"
What enrichment/formula is required to convert a string to number in Xceptor. I tried FormatNumber
You would need to add a calculation enrichment and then use the DECIMAL([string field]) function - description for this is - DECIMAL: Converts a text string to a decimal.
You can use the INTEGER function to convert a string to an integer
For example, TestInteger = INTEGER("7600")
More information can be found here Xceptor Docs - INTEGER Function
I'm struggling with an easy task. At least it looks like it should be, at first sight. I have a TextBox that contains HEX strings. They are always two hex digits in length (e.g. AA). I want to convert textbox3.Text to a Byte.
Here's what I have so far:
Dim checking As String = textbox3.Text
Dim a = Convert.ToByte(checking)
RichTextBox1.Text = a.ToString
But it throws a SystemFormatException.
The Convert.ToByte method provides an overload which takes a string argument followed by a number specifying the base of the value in the string. Hexadecimal is base-16. So, for instance:
Dim checking As String = textbox3.Text
Dim a As Byte = Convert.ToByte(checking, 16)
RichTextBox1.Text = a.ToString()
Any idea how i can separate a string with character and numbers, for example
12345ABC678 to make it look like this
1|2|3|4|5|A|B|C|6|7|8??
Or if this is not possile, how can i take this string a put every character or nr of it in a different textBox like this?
You can use String.Join and String.ToCharArray:
string input = "12345ABC678";
string result = String.Join("|", input.ToCharArray());
Instead of ToCharArray(creates a new array) you could also cast the string to IEnumerable<char> to force it to use the right overload of String.Join:
string result = String.Join("|", (IEnumerable<char>)input);
use
String aString = "AaBbCcDd";
var chars = aString.ToCharArray();
Then you can loop over the array (chars)
I want to know that is it possible to convert String into char, int,float,double and other primitive types
If yes then How.. If no then why..we can't do it.
In primitive type we can convert any primitive into any other using Type Casting..so Is there Something to do so with the Strings. As we know that we can convert any primitive type into String ,so is it possible to convert String into Primitive types..
Of course it is possible in java. As you know String is a class in java. this String class defines a method toCharArray() which is used to convert a String object to character array. Its return type is array of characters.
String str = "java";
char arr[];
arr = str.toCharArray();
Just use:
String str = "myString";
char[] charArray = str.toCharArray();
Finally found some really easy and working way..to convert String into Primitive Types...
We Can use wrapper class for conversion
But we have pay extra attention converting String into Primitive Types because we can only convert String into the requires primitive type if primitive type actually supports the data....i.e we can't convert a String into int if it's no(0 to 9),
any other data will throw runtime exception...Same will be applied to all other Primitive Types
//String to primitive types
int iVal = Integer.parseInt(str);
long lVal = Long.parseLong(str);
float fVal = Float.parseFloat(str);
double dVal = Double.parseDouble(str);
