Java ShortBuffer equals()用法及代码示例

java.nio.ShortBuffer类的equals()方法用于检查给定的缓冲区是否等于另一个对象。

当且仅当两个短缓冲区相等时，

它们具有相同的元素类型，
它们具有相同数量的剩余元素，并且
其余元素的两个序列(与它们的起始位置无关)是按点排列的
等于。

短缓冲区不等于任何其他类型的对象。

用法：

public boolean equals(Object ob)

参数：此方法将ob(与该缓冲区进行比较的对象)作为参数。

返回值：仅当此缓冲区等于给定对象时，此方法返回true。

下面是说明equals()方法的示例：

程序1：

// Java program to demonstrate 
// equals() method 
  
import java.nio.*; 
import java.util.*; 
  
public class GFG { 
  
    public static void main(String[] args) 
    { 
  
        // Declaring the capacity of the ShortBuffer 1 
        int capacity1 = 10; 
  
        // Declaring the capacity of the ShortBuffer 2 
        int capacity2 = 10; 
  
        // Creating the ShortBuffer 
        try { 
  
            // creating object of Shortbuffer 1 
            // and allocating size capacity 
            ShortBuffer sb1 = ShortBuffer.allocate(capacity1); 
  
            // creating object of Shortbuffer 2 
            // and allocating size capacity 
            ShortBuffer fb2 = ShortBuffer.allocate(capacity2); 
  
            // putting the value in Shortbuffer 1 
            sb1.put((short)856); 
            sb1.put(2, (short)961); 
            sb1.rewind(); 
  
            // putting the value in Shortbuffer 2 
            fb2.put((short)856); 
            fb2.put(2, (short)961); 
            fb2.rewind(); 
  
            // print the ShortBuffer 1 
            System.out.println(" ShortBuffer 1: "
                               + Arrays.toString(sb1.array())); 
  
            // print the ShortBuffer 2 
            System.out.println(" ShortBuffer 2: "
                               + Arrays.toString(fb2.array())); 
  
            // checking the equality of both ShortBuffer 
            boolean fbb = sb1.equals(fb2); 
  
            // checking if else condition 
            if (fbb) 
                System.out.println("both are equal"); 
            else
                System.out.println("both are not equal"); 
        } 
  
        catch (IllegalArgumentException e) { 
            System.out.println("IllegalArgumentException catched"); 
        } 
  
        catch (ReadOnlyBufferException e) { 
            System.out.println("ReadOnlyBufferException catched"); 
        } 
    } 
}

输出：

ShortBuffer 1: [856, 0, 961, 0, 0, 0, 0, 0, 0, 0]
ShortBuffer 2: [856, 0, 961, 0, 0, 0, 0, 0, 0, 0]

both are equal

程序2：

// Java program to demonstrate 
// equals() method 
  
import java.nio.*; 
import java.util.*; 
  
public class GFG { 
  
    public static void main(String[] args) 
    { 
  
        // Declaring the capacity of the ShortBuffer 1 
        int capacity1 = 10; 
  
        // Declaring the capacity of the ShortBuffer 2 
        int capacity2 = 5; 
  
        // Creating the ShortBuffer 
        try { 
  
            // creating object of Shortbuffer 1 
            // and allocating size capacity 
            ShortBuffer sb1 = ShortBuffer.allocate(capacity1); 
  
            // creating object of Shortbuffer 2 
            // and allocating size capacity 
            ShortBuffer sb2 = ShortBuffer.allocate(capacity2); 
  
            // putting the value in Shortbuffer 1 
            sb1.put((short)856); 
            sb1.put(2, (short)961); 
            sb1.rewind(); 
  
            // putting the value in Shortbuffer 2 
            sb2.put((short)856); 
            sb2.put(2, (short)431); 
            sb2.rewind(); 
  
            // print the ShortBuffer 1 
            System.out.println(" ShortBuffer 1: "
                               + Arrays.toString(sb1.array())); 
  
            // print the ShortBuffer 2 
            System.out.println(" ShortBuffer 2: "
                               + Arrays.toString(sb2.array())); 
  
            // checking the equality of both ShortBuffer 
            boolean fbb = sb1.equals(sb2); 
  
            // checking if else condition 
            if (fbb) 
                System.out.println("both are equal"); 
            else
                System.out.println("both are not equal"); 
        } 
  
        catch (IllegalArgumentException e) { 
            System.out.println("IllegalArgumentException catched"); 
        } 
  
        catch (ReadOnlyBufferException e) { 
            System.out.println("ReadOnlyBufferException catched"); 
        } 
    } 
}

输出：

ShortBuffer 1: [856, 0, 961, 0, 0, 0, 0, 0, 0, 0]
ShortBuffer 2: [856, 0, 431, 0, 0]

both are not equal
