方法详细资料

nvl

public static <T> T nvl(T obj,
                        T obj2)

nvl2

public static <T> T nvl2(Object obj,
                         T obj2,
                         T obj3)

compareTwoObject

public static int compareTwoObject(Object operand,
                                   Object operand2)

compareTwoComparableObject

public static <T extends Comparable<? super T>> int compareTwoComparableObject(T l1,
                                                                               T l2)

int compare(final T c1, final T c2) 等价于 ObjectUtils.compare

类型参数:

T - 比较对对象类型

参数:

l1 - 参数1

l2 - 参数2

返回:

返回比较值 0 相等 1 大于 -1 小于

参数:

a - object1

b - object2

返回:
