Java Array setShort()用法及代碼示例

java.lang.reflect.Array.setShort()是Java中的內置方法，用於將指定的short值設置為給定對象數組的指定索引。

句法：

Array.setShort(Object []array,int index, short value)

參數：此方法采用3個參數：

• array:這是要更新的Object類型的數組。
• index:這是要更新的數組的索引。
• value:這是要在給定數組的給定索引處設置的short值。

異常：此方法引發以下異常：

• NullPointerException –當數組為null時。
• IllegalArgumentException–當給定的對象數組不是數組時。
• ArrayIndexOutOfBoundsException–如果給定的索引不在數組的大小範圍內。

下麵是Array.setShort()方法的實現：

示例1:

// Java code to demonstrate  
// setShort() method of Array class 
  
import java.lang.reflect.Array; 
public class GfG { 
    // main method 
    public static void main(String[] args) { 
          
        // Declaring and defining Short array 
        short b[] = {1,2,3,4}; 
        System.out.print("Befor Set : "); 
        // printing the array 
        for(short x : b){ 
            System.out.print(x + " "); 
        } 
        short value = 10; 
        // set method of class Array 
        Array.setShort(b, 1, value); 
          
        System.out.print("\nAfter Set : "); 
        // printing array 
        for(short x : b){ 
            System.out.print(x + " "); 
        } 
          
    } 
}

輸出：

Befor Set : 1 2 3 4 
After Set : 1 10 3 4

示例2:演示java.lang.NullPointerException

// Java code to demonstrate  
// setShort() method of Array class 
  
import java.lang.reflect.Array; 
public class GfG { 
    // main method 
    public static void main(String[] args) { 
          
        // Declaring and defining Short array to null 
        short b[] = null; 
        try{ 
            short s = 10; 
            Array.setShort(b,5,s); 
        } 
        catch(Exception e){ 
            System.out.println("Exception : " + e); 
        } 
          
    } 
}

輸出：

Exception : java.lang.NullPointerException

示例3:演示java.lang.ArrayIndexOutOfBoundsException

// Java code to demonstrate  
// setShort() method of Array class 
  
import java.lang.reflect.Array; 
public class GfG { 
    // main method 
    public static void main(String[] args) { 
          
        // Declaring and defining Short array 
        short b[] = {1,2,3,4}; 
        try{ 
            short s = 10; 
            Array.setShort(b,5,s); 
        } 
        catch(Exception e){ 
            System.out.println("Exception : " + e); 
        } 
          
    } 
}

輸出：

Exception : java.lang.ArrayIndexOutOfBoundsException

示例4:演示java.lang.IllegalArgumentException

// Java code to demonstrate  
// setShort() method of Array class 
import java.lang.reflect.Array; 
public class GfG { 
    // main method 
    public static void main(String[] args) { 
          
        // Declaring and defining Short variable 
        short b = 1; 
        try{ 
            short s = 10; 
            Array.setShort(b,5,s); 
        } 
        catch(Exception e){ 
            System.out.println("Exception : " + e); 
        } 
          
    } 
}

輸出：

Exception : java.lang.IllegalArgumentException: Argument is not an array
