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
