Java中的FloatBuffer equals()方法

可以使用equals()java.nio.FloatBuffer类中的方法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元素序列，则它们相等。equals()如果缓冲区相等，则该方法返回true，否则返回false。

演示此的程序如下所示-

示例

import java.nio.*;
import java.util.*;
public class Demo {
   public static void main(String[] args) {
      int n = 5;
      try {
         FloatBuffer buffer1 = FloatBuffer.allocate(n);
         buffer1.put(4.5F);
         buffer1.put(1.2F);
         buffer1.put(3.9F);
         buffer1.put(7.5F);
         buffer1.put(5.8F);
         buffer1.rewind();
         System.out.println("The first FloatBuffer is: " + Arrays.toString(buffer1.array()));
         FloatBuffer buffer2 = FloatBuffer.allocate(n);
         buffer2.put(4.5F);
         buffer2.put(1.2F);
         buffer2.put(3.9F);
         buffer2.put(7.5F);
         buffer2.put(5.8F);
         buffer2.rewind();
         System.out.println("The second FloatBuffer is: " + Arrays.toString(buffer2.array()));
         boolean flag = buffer1.equals(buffer2);
         if (flag)
            System.out.println("\nBoth the buffers are equal");
         else
            System.out.println("\nBoth 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-

输出结果

The first FloatBuffer is: [4.5, 1.2, 3.9, 7.5, 5.8]
The second FloatBuffer is: [4.5, 1.2, 3.9, 7.5, 5.8]
Both the buffers are equal
