Java ShortBuffer equals()用法及代碼示例

java.nio.ShortBuffer類的equals()方法用於檢查給定的緩衝區是否等於另一個對象。

當且僅當兩個短緩衝區相等時，

它們具有相同的元素類型，
它們具有相同數量的剩餘元素，並且
其餘元素的兩個序列(與它們的起始位置無關)是按點排列的
等於。

短緩衝區不等於任何其他類型的對象。

用法：

public boolean equals(Object ob)

參數：此方法將ob(與該緩衝區進行比較的對象)作為參數。

返回值：僅當此緩衝區等於給定對象時，此方法返回true。

下麵是說明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"); 
        } 
    } 
}

輸出：

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"); 
        } 
    } 
}

輸出：

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

both are not equal
