场景:
    将Object数组转换为指定类型数组
1.转换函数

	public static <T> T[] convertArray(Class<T> targetType, Object[] arrayObjects) {
        if (targetType == null) {
            return (T[]) arrayObjects;
        }
        if (arrayObjects == null) {
            return null;
        }
        T[] targetArray = (T[]) Array.newInstance(targetType, arrayObjects.length);
        try {
            System.arraycopy(arrayObjects, 0, targetArray, 0, arrayObjects.length);
        } catch (ArrayStoreException e) {
        	e.printStackTrace();
        }
        return targetArray;
    }

2.测试main函数

	public static void main(String []args){

		 GirlVo girlVo =new GirlVo();
		 girlVo.setGirlId("08123");
		 girlVo.setGirlName("张一");
		 GirlVo girlVo2 =new GirlVo();
		 girlVo2.setGirlId("08456");
		 girlVo2.setGirlName("张二");
		 Object[] arrayObjects2 = new Object[2];
		 arrayObjects2[0] = girlVo;
		 arrayObjects2[1] = girlVo2;
		 
		 GirlVo[] arrayObjects3 ;
		 arrayObjects3 = convertArray(GirlVo.class,arrayObjects2);
		 for(int i=0;i<arrayObjects3.length;i++){
			 System.out.println("输出GirlVo: "+arrayObjects3[i].toString());
		 }
	}

3.实体类

public class GirlVo implements Serializable {
	 
	private static final long serialVersionUID = -8545755852948661858L;
	
	/**ID号*/
	String girlId;
	/**姓名*/
	String girlName;
	/**年龄*/
	long age;
	/**身高*/
	double height;
	/**罩杯*/
	String cupSize;
	public String getGirlId() {
		return girlId;
	}
	public void setGirlId(String girlId) {
		this.girlId = girlId;
	}
	public String getGirlName() {
		return girlName;
	}
	public void setGirlName(String girlName) {
		this.girlName = girlName;
	}
	public long getAge() {
		return age;
	}
	public void setAge(long age) {
		this.age = age;
	}
	public double getHeight() {
		return height;
	}
	public void setHeight(double height) {
		this.height = height;
	}
	public String getCupSize() {
		return cupSize;
	}
	public void setCupSize(String cupSize) {
		this.cupSize = cupSize;
	}
 
	@Override
	public String toString() {
		
		return "GirlVo [girlId=" + girlId
				+",girlName=" + girlName
				+",age=" + age
				+",height=" + height
				+",cupSize=" + cupSize
				+"]";
	}
}

以上,TKS.
