The following table shows the maximum allowed values for the numerical and decimal literals. String − These are text literals which are represented in the form of chain of characters. For example: Property names must be double-quoted strings trailing commas are forbidden. An example is ‘a’.īoolean − This represents a Boolean value which can either be true or false. Share Improve this answer I am very new with groovy scripts. An example is 12.3456565.Ĭhar − This defines a single character literal. An example is 12.34.ĭouble − This is used to represent 64-bit floating point numbers which are longer decimal number representations which may be required at times. An example is 10000090.įloat − This is used to represent 32-bit floating point numbers. Long − This is used to represent a long number. Int − This is used to represent whole numbers. Short − This is used to represent a short number. ![]() Following is a list of data types which are defined in Groovy −īyte − This is used to represent a byte value. Groovy offers a wide variety of built-in data types. Based on the data type of a variable, the operating system allocates memory and decides what can be stored in the reserved memory. You may like to store information of various data types like string, character, wide character, integer, floating point, Boolean, etc. This means that when you create a variable you reserve some space in memory to store the value associated with the variable. Variables are nothing but reserved memory locations to store values. The if-else statement is commonly used for conditional logic based on Boolean values.In any programming language, you need to use various variables to store various types of information. Groovy provides standard logical operators like & (AND), || (OR), and ! (NOT) to manipulate Boolean values. These are the only two values a Boolean can hold. It's fundamental for controlling the flow of your program through conditional statements.īoolean variables can be initialized to either true or false. The argument can be int, float, long, double. 7: abs() The method gives the absolute value of the argument. parseXxx() is a static method and can have one argument or two. 6: parseInt() This method is used to get the primitive data type of a certain String. ![]() ![]() In Groovy, the Boolean data type is used to represent true or false values. As a rule of thumb, if the number is floating point based (double, float, BigDecimal) there will be an implicit type conversion between each other, and the code will throw an exception when trying to convert to non-floating point numbers (like int or long). The method is used to get a String object representing the value of the Number Object. println "Line 1\nLine 2" // Output: Line 1 (newline) Line 2 Special characters like newlines and tabs can be included using escape sequences such as \n for a new line and \t for a tab. Println "Hello, $" // Output: Hello, John This allows you to embed variables directly within the string. Some simple Kotlin and Groovy language differences can make converting scripts tedious: Groovy strings can be quoted with single quotes string or double. Groovy supports string interpolation in GStrings. String result = str1 + " " + str2 // Output: Hello World You can concatenate strings using the + operator or the << left-shift operator. Println str.substring(1, 4) // Output: roo Some commonly used methods include length(), charAt(), and substring(). Groovy offers a rich set of methods to manipulate strings. Single quotes create a basic string, while double quotes create a GString, which supports string interpolation. Strings can be initialized using either single quotes or double quotes. ![]() Just change the following line in your code and issue will disappear: content new String (bytes, 'UTF-8'). Strings are sequences of characters and can be manipulated in various ways. The same problem with String.getBytes () - use charset parameter to get correct byte sequence. In Groovy, the String data type is one of the most versatile types you'll encounter. Groovy allows implicit type conversion for number types. It's the default choice for floating-point numbers. The difference is, that when one uses 'format', then there is a template, which can be formatted multiple times with different arguments, and it may happen in totally. The double type is a 64-bit number with a decimal point. Even though string interpolation could do the job in most cases, where string formatting is done, but it is not 100 replacement (especially the way, it is explained here). The float type is a 32-bit number with a decimal point. The long type provides the largest range, using 64 bits. The int type is the most commonly used, with 32 bits and a range from approximately -2 billion to 2 billion. The short type uses 16 bits and ranges from -32,768 to 32,767. The byte type takes 8 bits and has a range from -128 to 127. Floating-point types consist of float and double. Integer types include byte, short, int, and long. In Groovy, number data types are categorized into two main types: integer and floating-point.
