ShortBuffer equals() 方法在 Java 中
使用 java.nio.ShortBuffer 类中的 equals() 方法可以检查两个缓冲区的相等性。如果两个缓冲区具有相同类型的元素、相同数量的元素和相同的元素序列,则它们是相等的。equals() 方法在缓冲区相等时返回 true,否则返回 false。
以下是一个展示它的程序 -
示例
import java.nio.*; import java.util.*; public class Demo { public static void main(String[] args) { int n = 5; try { ShortBuffer buffer1 = ShortBuffer.allocate(n); buffer1.put((short)12); buffer1.put((short)91); buffer1.put((short)25); buffer1.put((short)18); buffer1.put((short)30); buffer1.rewind(); System.out.println("The first ShortBuffer is: " + Arrays.toString(buffer1.array())); ShortBuffer buffer2 = ShortBuffer.allocate(n); buffer2.put((short)12); buffer2.put((short)91); buffer2.put((short)25); buffer2.put((short)18); buffer2.put((short)30); buffer2.rewind(); System.out.println("The second ShortBuffer is: " + Arrays.toString(buffer2.array())); boolean flag = buffer1.equals(buffer2); if (flag) System.out.println("
Both the buffers are equal"); else System.out.println("
Both the buffers are not equal"); } catch (IllegalArgumentException e) { System.out.println("Error!!! IllegalArgumentException"); } catch (ReadOnlyBufferException e) { System.out.println("Error!!! ReadOnlyBufferException"); } } }
上面程序的输出如下 -
输出
The first ShortBuffer is: [12, 91, 25, 18, 30] The second ShortBuffer is: [12, 91, 25, 18, 30] Both the buffers are equal
