Starts With( ) and ends With( ) Java Help

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 str) Boolean With (String srr)  Here; str is the String being tested. If the string matches, true is returned. Otherwise, false is returned. For example, are both true. A second form of starts With( ), shown here, lets you specify a starting point: Here, standardize specifies the index into the invoking string at which point the search will begin. For example

equals( ) Versus’

It is important to understand that the equals ) method .and the operator perform two different operations. As just explained, the equals ) method compares the characters inside a String object. The operator compares two object references to see whether they refer to the same instance. The following program shows how two different String objects can contain the characters, but references to these objects will not compare as equal:

 The variable s1 refers to the String instance created by “Hello”. The object referred Toby 52 is created with 51 as initialize: Thus, the contents of the two String objects are identical, but they are distinct objects. This means that 51 and .52 do not refer to the same objects and are, therefore.not ==,’as is shown hereby the output of the preceding example
