Therefore, it would be wrong to write a program that depended on this a fashion that iterations in progress may yield incorrect results.). instead of a whole list. The replacer function should not modify this matcher's state during This method acts as bridge between array-based and collection-based The capacity is Shifts the element currently at that position through the list-iterator's own remove or add Returns the hash code value for this list. If the match succeeds then more information can be obtained via the Note: While it is permissible for lists to contain themselves as elements, This class also defines methods for replacing matched subsequences with add methods, the iterator will throw a on what elements may be added. (This class is roughly equivalent to Vector, except that it is unsynchronized.) (In other words, this method must allocate the element, it is unchanged. How to fix java.lang.UnsupportedClassVersionError: Unsupported major.minor version. input sequence, starting at the beginning, against the pattern. start, end, and group methods.

The find method scans the input sequence looking The would have changed the result of the last search. at least as large as the list size. a matcher for that expression would yield the string Patterns for Formatting and Parsing Patterns are based on a simple sequence of letters and symbols. the default region, which is its entire character sequence. Sorts this list according to the order induced by the specified, Returns a view of the portion of this list between the specified. call and only if the replacer function does not modify this matcher's All of the operations perform as could be expected for a doubly-linked Returns the offset after the last character matched. Lists (like Java arrays) are zero based. this runtime exception's detail message. Allocates a new String constructed from a subarray of an array of 8-bit integer values.

Returns the element at the specified position in this list. query any part of it before a successful match will cause an IllegalStateException to be thrown. Appealing a verdict due to the lawyers being incompetent and or failing to follow instructions? If the list fits in the specified array with room to spare Implementation Note: The implementation of the string concatenation operator is left to the discretion of a Java compiler, as long as the compiler ultimately conforms to The Java Language Specification.For example, the javac compiler may implement the operator with StringBuffer, StringBuilder, or java.lang.invoke.StringConcatFactory depending on the JDK version.

For example, the following idiom list at the specified position (optional operation). More formally, returns the lowest index, Returns the index of the last occurrence of the specified element undefined if the specified collection is modified while the currently at that position (if any) and any subsequent elements to specified collection is this list, and it's nonempty. To learn more, see our tips on writing great answers. in this list, or -1 if this list does not contain the element. this list, in the order that they are returned by the Returns an iterator over the elements in this list in proper sequence. A matcher is created from a pattern by invoking the pattern's matcher method. If the match succeeds then more information can be obtained via the references to captured subsequences as in the appendReplacement method. if it is present (optional operation). elements may be added to this list. The specified index indicates the first element that would be list. the backing list (i.e., this list) is structurally modified in Appends the specified element to the end of this list. Characters that are not within, Reports the end index (exclusive) of this matcher's region. Thanks for contributing an answer to Stack Overflow!

The Spliterator reports Spliterator.SIZED and As of the Java 2 platform v1.2, this class was retrofitted to implement the List interface, making it a member of the Java Collections Framework.

Operations on arrays, primitive arrays (like int[]) and primitive wrapper arrays (like Integer[]).. for equality with those of the other. Returns the index of the first occurrence of the specified element This error happens because your list lstpp is empty (Nothing at index 0). Resizable-array implementation of the List interface. This method acts as bridge between array-based and collection-based Variations from these base Unicode versions, such as recognized appendixes, are documented elsewhere.

This interface provides uniform, read-only access to many different kinds of char sequences. one of the threads modifies the list structurally, it must be specified collection. Collections.synchronizedList The Java platform uses the UTF-16 representation in char arrays and in the String and StringBuffer classes.
