flip()方法有两种变体。本文介绍了所有这些内容,如下所示:
1. flip(int value):此方法删除参数中指定的值。
public void flip(int value) 参数: value: the value to flip. Return ValueThis method does not return a value.
// Java code to demonstrate the
// working of flip(int value) in Bitset
import java.util.*;
public class Flip1 {
public static void main(String[] args) {
// declaring bitset
BitSet bset = new BitSet(6);
// assigning values to bset
bset.set(0);
bset.set(1);
bset.set(2);
bset.set(3);
// printing the original set
System.out.println("The original bitset is:" + bset);
// using flip() to remove 2
bset.flip(2);
// printing final bitset
// 2 is removed
System.out.println("The flipped bitset is:" + bset);
}
}
输出:
The original bitset is:{0, 1, 2, 3} The flipped bitset is:{0, 1, 3}
2. flip(int fromnum,int tonum):此方法将指定的fromnum(包括)到指定的tonum(不包括)中的每个位设置为其当前值的补码,即将fromnum删除为tonum-1的值。
public void flip(int fromnum,int tonum) 参数: fromnum: start number to begin flipping. tonum: last-1 number to end flipping. 返回值: This method does not return a value.
// Java code to demonstrate the
// working of flip(int fromnum, int tonum) in Bitset
import java.util.*;
public class Flip2 {
public static void main(String[] args) {
// declaring bitset
BitSet bset = new BitSet(6);
// assigning values to bset
bset.set(0);
bset.set(1);
bset.set(2);
bset.set(3);
// printing the original set
System.out.println("The original bitset is:" + bset);
// using flip(fromnum,tonum) to remove 1 and 2
bset.flip(1,3);
// printing final bitset
// 1 and 2 are removed
System.out.println("The flipped bitset is:" + bset);
}
}
输出:
The original bitset is:{0, 1, 2, 3} The flipped bitset is:{0, 3}
