What is the difference between functions and variables?
Variables define a certain value, such as an integer, string, boolean value, etc. Functions are defined to run a certain task, and may or may not return a value. You can have a function that calculates the sum of two numbers and returns the sum once calculated.
Is String class a final class?
The core classes in the java.lang.* package (e.g. String, Integer, double, Boolean, etc.) are all declared final.
How do you get boolean value from string in java?
Here is some sample code to convert a string into a boolean: String word = "true"; boolean boo; if (word.equalsIgnoreCase("true")) boo=true; else boo=false;
What is the simularities of parameter and arguments?
Arguments are fields that are given to a method when it is called, while parameters are the name for the received variables. For example:public static void main(String[] args){int arg1 = 0;boolean arg2 = false;String arg3 = "Some string";function_a(arg1, arg2, arg3);// These variables are called arguments because they are being passed// to the function.}public static void function_a(int par1, boolean par2, String par3){// These variables are called parameters because they are being received// when the function is called.}I hope this helps.
What are the variables in vb?
The variables is visual basic are the items being declared in order to use within the program, for example if you were writing a program for the SUVAT equations the variables would be difined as follows... Dim is as integer Dim iu as integer Dim iV as integer e.c.t Think of the Dim to mean declare and the "as integer" is the data type. If it was a text value (string) for example a name it would be declared as follows: Dim sname as string where sname is the variable. For an array of values you would do the same but as follows: dim sname(100) as string this would create a space so to speak for 101 (0-100) names which would be inputted as so: sname(0) = Dan sname(1) = Sarah e.c.t hope that helps without being to complicated
Declare and initialize variables of int double char boolean and String?
public class Test { int i = 0; double d = 0; char c = 'A'; boolean val = true; String str = "Rocky"; ....... ...... ..... }
Can you compare a boolean to an integer?
no, you cant. it only works on string

What is the prefix for variable?
In programming, the term "prefix" typically refers to a naming convention that precedes the name of a variable. Common prefixes include "int" for integer variables, "str" for string variables, "bool" for boolean variables, and so on. These prefixes help developers quickly identify the data type of a variable.
How can you check if a variable is a string or an integer in PHP?
Integers - The "is_int()" function can be used to check if a variable is has an integer for its value. ---- is_int($variable); // Returns true if $variable is an integer - otherwise false ---- Numeric Strings - Numeric strings are strings with numbers (or things that count as numbers) in them. Numeric-string variables are not integer variables. Numeric-string variables are passed on through forms, instead of integer variables - if you were wondering. Check form values using string formats, and not integer formats. The "is_numeric()" function can be used to check if a variable is a string with numbers - and only numbers - in it (except things that add up to be numbers). ---- is_numeric($variable); // Returns true if $variable is a string, and only contains numbers (broadly speaking) - false otherwise ---- Strings - String values are just text, basically. String variables can contain integers, but that does not make it an integer-type variable - it makes it a numeric string variable. The "is_string" function can be used to check if a variable contains the value of a string. ---- is_string($variable); // Returns true if $variable is a string - false otherwise

How does the absolute beginner to Browser-side scripting supposed to know what boolean or string means?
Boolean means yes or no, true or false, 0 or 1. There can only be 2 alternatives in boolean. In JavaScript there is a function typeof which will show whether variable is boolean, string, integer or any other. I am providing a few examples. Try those and you will understand what type of variable is providedvar a = 12;alert("Variable is of type: "+typeof(a));var a = "hello";alert("Variable is of type: "+typeof(a));
Can you store non primitive data type in the array list?
Yes you can store non primitive data type variables in an array. String is a non primitive data type. You can declare a string array as: String a[]=new String[10];
