1、轉換為字符串
int a = 1;
//aStr為"1"
String aStr = Convert.toStr(a);
long[] b = {1,2,3,4,5};
//bStr為："[1, 2, 3, 4, 5]"
String bStr = Convert.toStr(b);
2、轉換為指定類型數組
String[] b = { "1", "2", "3", "4" };
//結果為Integer數組
Integer[] intArray = Convert.toIntArray(b);
long[] c = {1,2,3,4,5};
//結果為Integer數組
Integer[] intArray2 = Convert.toIntArray(c);
3、轉換為日期對象
String a = "2017-05-06";
Date value = Convert.toDate(a);
4、轉換為集合
Object[] a = {"a", "你", "好", "", 1};
List<?> list = Convert.convert(List.class, a);
List<?> list = Convert.toList(a);
