Java 中 IntBuffer equals() 方法
可以使用类 java.nio.IntBuffer 中的方法 equals() 来检查两个缓冲区的相等性。如果两个缓冲区具有相同的元素类型、相同的元素数和相同的元素序列,则它们相等。如果缓冲区相等,方法 equals() 返回 true,否则返回 false。
下面给出一个展示此方法的程序 −
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");
}
}
}上述程序的输出如下 −
输出
The first IntBuffer is: [8, 1, 3, 7, 5] The second IntBuffer is: [8, 1, 3, 7, 5] Both the buffers are equal
