Java 中的排序器 getOffset()方法，带示例
原文:https://www . geeksforgeeks . org/collectionelementiterator-get offset-method-in-Java-with-examples/
Java . text . CollationElementIterator 类的 getOffset() 方法用于获取当前由 collectionelementiterator 指向的排序器中存在的项的索引。
语法:
public int getOffset()
参数:此方法不接受任何参数。
返回值:该方法返回迭代器当前指向的元素的偏移量。
以下是说明 getOffset() 方法的示例:
例 1:
// Java program to demonstrate getOffset() method
import java.text.*;
import java.util.*;
import java.io.*;
public class GFG {
public static void main(String[] argv)
{
// creating and initializing testString
String test = "Code Geeks 123";
// creating and initializing
// RuleBasedCollator object
RuleBasedCollator rbc
= (RuleBasedCollator)(Collator.getInstance());
// creating and initializing
// CollationElementIterator
CollationElementIterator cel
= rbc.getCollationElementIterator(test);
// setting offset to index 4
cel.setOffset(4);
// getting offset of cel
// using getOffset() method
int value = cel.getOffset();
// display the result
System.out.println("current offset is "
+ value);
}
}
输出:
current offset is 4
例 2:
// Java program to demonstrate getOffset() method
import java.text.*;
import java.util.*;
import java.io.*;
public class GFG {
public static void main(String[] argv)
{
// creating and initializing testString
String test = "Code Geeks 123";
// creating and initializing
// RuleBasedCollator object
RuleBasedCollator rbc
= (RuleBasedCollator)(Collator.getInstance());
// creating and initializing
// CollationElementIterator
CollationElementIterator cel
= rbc.getCollationElementIterator(test);
// setting offset to index 4
cel.setOffset(4);
// calling next element
cel.next();
// getting offset of cel
// using getOffset() method
int value = cel.getOffset();
// display the result
System.out.println("current offset is "
+ value);
}
}
输出:
current offset is 5
