c bitset get

BitSet类的get()方法 (BitSet Class get() method)

Syntax:

句法：

    public boolean get(int bit_in);
public BitSet get(int st_in, int en_in);

• get() method is available in java.util package.

  get()方法在java.util包中可用。

• get(int bit_in) method is used to return the value of the given bit indices (bit_in). It returns true when the bit with the given index is set by using the set() method.

  get(int bit_in)方法用于返回给定位索引(bit_in)的值。 当使用set()方法设置具有给定索引的位时，它返回true。

• get(int st_in, int en_in) method is used to returns a subset consisted of bits from this BitSet from the given range st_in(starting index) and en_in(ending index).

  get(int st_in，int en_in)方法用于从给定范围st_in (起始索引)和en_in (结束索引)返回该BitSet中的位组成的子集。

• get(int bit_in) method may throw an exception at the time of checking index.

  在检查索引时， get(int bit_in)方法可能会引发异常。

  IndexOutOfBoundsException: This exception may throw when the given index is less than 0.

  IndexOutOfBoundsException ：当给定索引小于0时，可能引发此异常。

• get(int st_in, int en_in) method may throw an exception at the time of checking exception.

  在检查异常时， get(int st_in，int en_in)方法可能会引发异常。

  IndexOutOfBoundsException: This exception may throw when st_in or en_in is less than 0 or st_in > en_in.

  IndexOutOfBoundsException ：当st_in或en_in小于0或st_in> en_in时，可能引发此异常。

• These are non-static methods, so it is accessible with the class object and if we try to access these methods with the class name then we will get an error.

  这些是非静态方法，因此可以通过类对象进行访问，如果尝试使用类名称访问这些方法，则会收到错误消息。

Parameter(s):

参数：

• In the second case, get(int bit_in)

  在第二种情况下， get(int bit_in)

  • int bit_in – represents the bit index.
  • int bit_in –表示位索引。

• In the third case, get(int st_in, int en_in)

  在第三种情况下， get(int st_in，int en_in)

  • int st_in – represent the starting bit(st_in) to conclude.
  • int st_in –表示要结束的起始位(st_in)。

Return value:

返回值：

In the first case, boolean get(bit_in): The return type of the method is boolean, it returns true when it returns the value of the bit of the given index.

在第一种情况下， boolean get(bit_in) ：方法的返回类型为boolean ，当它返回给定索引的bit值时返回true。

In the second case, BitSet get(int st_in, int en_in), it returns BitSet of the given range (st_in & en_in).

在第二种情况下， BitSet get(int st_in，int en_in) ，它返回给定范围( st_in＆en_in )的BitSet。

Example:

例：

// Java program to demonstrate the example 
// of get() method of BitSet.
import java.util.*;
public class GetOfBitSet {
public static void main(String[] args) {
// create an object of BitSet
BitSet 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);
bs.set(60);
bs.set(70);
bs.set(80);
// Display Bitset
System.out.println("bs: " + bs);
// By using get(40) method is used to 
// check the given bit exists in this BitSet or not
boolean status = bs.get(40);
// Display status
System.out.println("bs.get(40): " + status);
// By using get(40,60) method is used to 
// check the given set of bits exists in this
// BitSet or not
// Display Bitset
System.out.println("bs.get(40,60): " + bs.get(40, 60));
}
}

Output

输出量

bs: {10, 20, 30, 40, 50, 60, 70, 80}
bs.get(40): true
bs.get(40,60): {0, 10}
