Java ผมต้องการแปลง int ให้กลายเป็น Number ทำอย่างไรครับ

int arrData[][] = {{...},{...},{...},...};
		
Number[] Num1 = new Number[arrData.length];
Number[] Num2 = new Number[arrData.length];
int i,tmp;
Integer[] intObj = new Integer[arrData.length];

for(i=0;i<arrData.length;i++){
	tmp = arrData[i][0];
	intObj[i] = new Integer(tmp);  
	Num1[i] = (Number)intObj[i]; 
	tmp = arrData[i][1];
	intObj[i] = new Integer(tmp);  
	Num2[i] = (Number)intObj[i]; 
}
