java bitset
BitSet類nextSetBit()方法 (BitSet Class nextSetBit() method)
nextSetBit() method is available in java.util package.
nextSetBit()方法在java.util包中可用。
nextSetBit() method is used to retrieve the index of the first bit that is set to true that occurs or searching starts after the given src_in.
nextSetBit()方法用于檢索在給定的src_in之后出現或開始搜索的設置為true的第一位的索引。
nextSetBit() method is a non-static method, so it is accessible with the class object and if we try to access the method with the class name then we will get an error.
nextSetBit()方法是一種非靜態方法,因此可以通過類對象進行訪問,如果嘗試使用類名訪問該方法,則會收到錯誤消息。
nextSetBit() method may throw an exception at the time of checking the given index.
在檢查給定索引時, nextSetBit()方法可能會引發異常。
IndexOutOfBoundsException: This exception may throw when the given index is less than 0.
IndexOutOfBoundsException :當給定索引小于0時,可能引發此異常。
Syntax:
句法:
public int nextSetBit(int src_in);Parameter(s):
參數:
int src_in – represents the searching index (src_in) to start searching from.
int src_in –表示要從其開始搜索的搜索索引(src_in)。
Return value:
返回值:
The return type of this method is int, it returns the index of first set bit to true or next set bit.
此方法的返回類型為int ,它將第一個設置位的索引返回為true或下一個設置位的索引。
Example:
例:
// Java program to demonstrate the example // of int nextSetBit(int src_in) method of BitSet.import java.util.*;public class NextSetBitOfBitSet {public static void main(String[] args) {// create an object of BitSetBitSet bs = new BitSet(10);// By using set() method is to set// the values in BitSet bs.set(10);bs.set(20);bs.set(30);bs.set(40);bs.set(50);// Display BitsetSystem.out.println("bs: " + bs);// By using nextSetBit(int) method is to return // the first bit after the given indexint next_set_bit = bs.nextSetBit(2);// Display next_set_bitSystem.out.println("bs.nextSetBit(2): " + next_set_bit);} }Output
輸出量
bs: {10, 20, 30, 40, 50} bs.nextSetBit(2): 10翻譯自: https://www.includehelp.com/java/bitset-nextsetbit-method-with-example.aspx
