若傳入?yún)?shù)值21~40,51~100,41~42,1~50（該參數(shù)類型可為string，string[]或list）合并結(jié)果為1~100,21~42（類型可同傳入?yún)?shù)）。傳入?yún)?shù)可以重復，如：21~40,51~100,41~42,1~50，1~50，返回結(jié)果也同上。

//new String[]{"21~40","51~100","41~42","1~50"}
public static Object merge(Object o)
{
if(o instanceof String[])
{
String[] numbers = (String[])o;
int resultLength = numbers.length;
for(int i = 0; i < numbers.length; i++)
{
if(numbers[i] == null) continue;
int start = getStart(numbers[i]);
int end = getEnd(numbers[i]);
if(start > end) continue;
for(int j = 0; j < numbers.length; j++)
{
if(i == j || numbers[j] == null) continue;
int nextStart = getStart(numbers[j]);
int nextEnd = getEnd(numbers[j]);
if(start == (nextEnd + 1))
{
numbers[i] = nextStart + delimiter + end;
numbers[j] = null;
resultLength--;
}
}
}
String[] result = new String[resultLength];
int index = 0;
for(int i = 0; i < numbers.length; i++)
{
if(numbers[i] == null) continue;
result[index++] = numbers[i];
System.out.println(numbers[i]);
}
return result;
}
return null;
}只寫了string[]類型的，list等參數(shù)類型按照這個思路自己補充就行了

忘記兩個方法了
[code="java"]
private static final String delimiter = "~";
public static int getStart(String number)
{
String start = number.substring(0, number.indexOf(delimiter));
return Integer.valueOf(start);
}
public static int getEnd(String number)
{
String end = number.substring(number.indexOf(delimiter) + 1);
return Integer.valueOf(end);
