The same way you would in a regular java program.
int i = 10;
String s = i + "";
after the above line of code the variable s will have "10" as a string value...
To remove the decimal and numbers:select Convert(int,12.456)To keep the numbers after the decimal but remove the ".":select convert(int,convert(money,12.456)*1000)
JSP actions are XML tags that direct the server to use existing components or control the behavior of the JSP engine. JSP Actions consist of a typical (XML-based) prefix of "jsp" followed by a colon, followed by the action name followed by one or more attribute parameters. There are six JSP Actions: < jsp : include / > < jsp : forward / > < jsp : plugin / > < jsp : usebean / > < jsp : setProperty / > < jsp : getProperty / >
jsp means Java Server Pages.
In php to select a sub string from a string, use the command: string substr ( string string, int start [, int length]);Simple Examples:
The implicit objects in a JSP page are:requestresponsepageContextsessionapplicationoutconfigpage
One can convert a string variable to an int variable in Java using the parse integer command. The syntax is int foo = Integer.parseInt("1234"). This line will convert the string in the parenthesis into an integer.
int i= Convert.ToInt32("5");
There is no one line of code that can convert an array to a different type. A new String array would have to be created and values individually inserted into the array. Example: //Assume int[] i has been previously defined String[] s = new String[i.length]; for(int i=0; i<s.length; i++) s[i] = ""+i[i];
To convert string to int in Java, the easiest way is to simply use the method Integer.parseInt(). For more information how to do this, refer to the integer class documents.
Use the atoi() or atol() function.
int <integerName> = <integerValue>; String <StringName> = Integer.toString(<integerName>); /*where integerName is the name of the integer value, integerValue is the assigned value of the integer, and where StringName is the name of the string holding the parsed integer. */
That really depends on the programming language. In Java, it is sufficient to concatenate it with a String: int myNumber = 5; result = "" + myNumber; Other languages may require a special function, or method, to convert from integer to string.
I assume that your scanner is not scanning a string already, so if you are scanning an int then you can do: for the example you scanner variable is x .... x.intparseString();
lets say you have the following: Dim Int1 as Integer=12 Dim String1 as String 'Very Simple String1=Int1.tostring
Val() function is used in Visual Basic 6.0 to convert a string to a numeric value (such as integer, double etc.) or to extract a numeric value out of a string, as illustrated below.Val function as used to convert a string to a numeric valuefor example, let str be a string,Dim str as stringDim int as integerstr="09090"int=val(str)gives int = 9090also, used to extract the numeric part out of a following string,ie. a=val("98ASR_tyui") would give a=98however,b=val("The89")would give b=0 as there is no numeric value preceding the string.
int a; -- variable definition"int a" -- string literal
You declare a variable the same in a JSP as you do in a servlet. Let's say you want to declare a String variable called "foo" and you wanted to assign it a value of "bar." You would do this: String foo = "bar"; Of course, in a JSP, any Java code needs to be enclosed within <% and %>.
