A String object is returned, representing the substring of this string that begins with the character at index k and ends with the character at index m -that is, the result of this.substring (k, m + 1) . This method may be used to trim whitespace (as defined above) from the beginning and end of a string.If you want to represent any object as a string, toString() method comes into existence. The toString() method returns the string representation of the object. If you print any object, java compiler internally invokes the toString() method on the object. So overriding the toString() method, returns the desired output, it can be the state of an object etc. depends on your implementation.std:: to_string. std:: to_string.

Example: var o = {a:1, b:2}; console.log (o); console.log ('Item: ' + o); console.log ('Item: ', o); // :) Output:It says: The string representation must have the syntax of a FunctionDeclaration FunctionExpression, GeneratorDeclaration, GeneratorExpession, ClassDeclaration, ClassExpression, ArrowFunction, MethodDefinition, or GeneratorMethod depending upon the actual characteristics of the object. So for example 'toString ()' for the next class:class String. A String object has an arbitrary sequence of bytes, typically representing text or binary data. A String object may be created using String::new or as literals. String objects differ from Symbol objects in that Symbol objects are designed to be used as identifiers, instead of text or data.

Need to print the object for getting the details about the data type present within the object. print( object_strng)Strings are useful for holding data that can be represented in text form. Some of the most-used operations on strings are to check their length, to build and concatenate them using the + and += string operators, checking for the existence or location of substrings with the indexOf() method, or extracting substrings with the substring() method.A String object is a sequential collection of System.Char objects that represent a string; a System.Char object corresponds to a UTF-16 code unit. The value of the String object is the content of the sequential collection of System.Char objects, and that value is immutable (that is, it is read-only).Strings are constant; their values cannot be changed after they are created. String buffers support mutable strings. Because String objects are immutable they can be shared. For example: String str = "abc"; is equivalent to: char data [] = {'a', 'b', 'c'}; String str = new String (data);If you want to represent any object as a string, toString() method comes into existence.

You appear to be attempting to save a condition and action as strings within the properties of a node, where the condition defines a Cypher query and the action provides a conditionally performed query. Your method is correct, however you will need to employ dynamic Cypher query execution to do this. Strings are objects that represent sequences of characters. The standard string class provides support for such objects with an interface similar to that of a standard container of bytes, but adding features specifically designed to operate with strings of single-byte characters.We can annotate any class with the Lombok @ToString annotation. This modifies the generated bytecode and creates an implementation of the toString () method. By default, the @ToString annotation prints the class name, along with each non-static field name and its value obtained by calling the getter (if declared).How to use Arrays.toString () method? Description: Returns a string representation of the contents of the specified array. The string representation consists of a list of the array’s elements, enclosed in square brackets (“ []”). Adjacent elements are separated by the characters “, ” (a comma followed by a space). Returns “null ...This header introduces string types, character traits and a set of converting functions: Class templates basic_string Generic string class (class template) char_traitsTo turn a list of elements into a single string in C#, we will utilize the string.Join method, StringBuilder object, Enumerable.Aggregate method and the string concatenation operator. The string.Join method concatenates the elements of a specified array or the members of a collection, using the specified separator between each element or member.The reverseIt () method above uses StringBuffer's toString () method to convert the StringBuffer to a String object before returning the String. return dest.toString (); Several classes in the java.lang also support toString () including all of the "type wrapper" classes such as Character, Integer, Boolean and the others.Instead Class objects are constructed automatically by the Java Virtual Machine as classes are loaded and by calls to the defineClass method in the class loader.
