The reset() method of java.text.CollationElementIterator class is used to reset the cursor of the iterator to the beginning of the input string.
Syntax:
public void reset()
Parameter: This method does not accept any parameter.
Return Value: This method has nothing to return.
Below is the examples to illustrate the reset() method:
Example 1:
Java
// Java program to demonstrate// reset() methodimport java.text.*;import java.util.*;import java.io.*;public class GFG { public static void main(String[] argv) { // creating and initializing testString String test = "abcd"; // creating and initializing // RuleBasedCollator object RuleBasedCollator rbc = (RuleBasedCollator)(Collator.getInstance()); // creating and initializing // CollationElementIterator CollationElementIterator cel = rbc.getCollationElementIterator(test); // setting cursor of iterator cel.setOffset(2); cel.next(); // display the result System.out.println( "current offset before calling reset() " + cel.getOffset()); // reset the cursor to the // beginning of the string // using reset() method cel.reset(); // display the result System.out.println( "\ncurrent offset after calling reset() " + cel.getOffset()); }} |
Output:
current offset before calling reset() 3 current offset after calling reset() 0
Example 2:
Java
// Java program to demonstrate// reset() methodimport java.text.*;import java.util.*;import java.io.*;public class GFG { public static void main(String[] argv) { // creating and initializing // testString String test = "abcd"; // creating and initializing // RuleBasedCollator object RuleBasedCollator rbc = (RuleBasedCollator)(Collator.getInstance()); // creating and initializing // CollationElementIterator CollationElementIterator cel = rbc.getCollationElementIterator(test); // setting cursor of iterator cel.setOffset(3); cel.previous(); // display the result System.out.println( "current offset before calling reset() " + cel.getOffset()); // reset the cursor to the beginning of the string // using reset() method cel.reset(); // display the result System.out.println( "\ncurrent offset after calling reset() " + cel.getOffset()); }} |
Output:
current offset before calling reset() 2 current offset after calling reset() 0
