Java 中 IntBuffer equals() 方法
可以使用類 java.nio.IntBuffer 中的方法 equals() 來檢查兩個緩衝區的相等性。如果兩個緩衝區具有相同的元素型別、相同的元素數和相同的元素序列,則它們相等。如果緩衝區相等,方法 equals() 返回 true,否則返回 false。
下面給出一個展示此方法的程式 −
示例
import java.nio.*; import java.util.*; public class Demo { public static void main(String[] args) { int n = 5; try { IntBuffer buffer1 = IntBuffer.allocate(n); buffer1.put(8); buffer1.put(1); buffer1.put(3); buffer1.put(7); buffer1.put(5); buffer1.rewind(); System.out.println("The first IntBuffer is: " + Arrays.toString(buffer1.array())); IntBuffer buffer2 = IntBuffer.allocate(n); buffer2.put(8); buffer2.put(1); buffer2.put(3); buffer2.put(7); buffer2.put(5); buffer2.rewind(); System.out.println("The second IntBuffer 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"); } } }
上述程式的輸出如下 −
輸出
The first IntBuffer is: [8, 1, 3, 7, 5] The second IntBuffer is: [8, 1, 3, 7, 5] Both the buffers are equal
