Starts With( ) and ends With( )

Starts With( ) and ends With( ) String defines two routines that are, more or less, specialized forms of congregationalists] ). The starts With( ) method determines whether a given String begins with a specified string. Conversely, ends With() determines whether the String in, question ends with a specified string. They have the following general forms: Boolean starts With(String…

Equals() and countersignature( )

Equals() and countersignature( ) To compare two strings equality, use equals(). It has this general form: Boolean equals(Object st) Here, str is the String object being compared with the invoking String object. It returns – true if the strings contain the same characters in the same order, and false otherwise, The comparison is case-sensitive; ,To perform a.comparison that ignores case…

get Bytes ( )

get Bytes ( ) There is an alternative to get Chars() that stores the characters in array of bytes. This method is called get Bytes( ), and it uses the default character-to-byte conversions provided by the platform. Here is its simplest form: byte[ genetics() either forms of gel Bytes( ) are also available. gentlest ) is most useful when…

Character Extraction

Character Extraction  The String class provides a number of ways in which characters can be extracted from a String object. Each is examined here. Although the characters that comprise a string within a String object cannot’ be indexed as if they were a character array, many of the String methods employ an index (or offset) into the string…

String Conversion and to String( )

String Conversion and to String( )  When Java converts data into its string representation during concatenation, it does so. by’ calling one of the overloaded versions of the string conversion method value of the ) defined by String. value is overloaded for all the simple types and for type Object. For the simple types, value.Of( ) returns ”…

String Concatenation

String Concatenation  Tn general, Java does not allow operators to be applied to St,ring objects. The one , exception to this rule is the + operator, which concatenates two strings, producing ‘a String object as the result. This allows you to chain together n series of + operations . For example, the following fragment concatenates three strings: This…

Special String Operations

Special String Operations  Because strings are a common and important part of programming, Java has added special support for several string operations within the syntax of the language. These operations include the automatic creation of new ‘String instances from string literals, concatenation of multiple String objects by us,e of the +operator, and the conversion of other data types to…

The String Constructors

The String Constructors  The String class supports several constructors. To create an empty String, you call the default constructor, For example, This constructor initializes s with the string” abc”, You can specify a sub range of a character array as an initialize using the following constructor: Stringiness chars[ ], int start index, int  Mere, starring specifies the index at…

Staring Handling

Staring Handling brief overview of string handling was presented in this chapter, it is described in detail. As is the case in most other programming J languages, in Java a string is a sequence of characters. But, unlike many other languages that implement strings as character arrays, Java implements strings as – objects of type String. . Implementing…

Replace( )

Replace( ) Another new method added to String Buffer by Java 2 is replace ). It replaces one set of characters with another set inside a String Buffer object. Its signature is shown here: I String bluffer replace(int standstill, int extender, String str) , The sub string being replaced is specified by the indexes start index and endurance. Thus, the…
