Java中java.text.CharacterIterator接口的setIndex()方法用於設置由CharacterIterator讀取的當前索引。此方法將要設置的索引作為參數,並在該索引處設置此CharacterIterator的索引,然後返回該字符。
用法:
public char setIndex(int index)
參數:此方法將要設置的索引作為參數,並設置此CharacterIterator的索引。
返回值:此方法返回此方法設置的索引處的字符。
異常:如果指定的索引不在有效範圍內(getBeginIndex(),getEndIndex() – 1),則此方法引發IllegalArgumentException。
程序:
// Java program to demonstrate
// the above method
import java.text.*;
import java.util.*;
public class CharacterIteratorDemo {
public static void main(String[] args)
{
CharacterIterator characterIterator
= new StringCharacterIterator(
"GeeksForGeeks");
System.out.println("Current Index: "
+ characterIterator
.getIndex());
int index = 5;
System.out.println("Updated the index to : "
+ index);
System.out.println("Character at new"
+ " current index: "
+ characterIterator
.setIndex(index));
}
}
輸出:
Current Index: 0 Updated the index to : 5 Character at new current index: F
