用WINRAR打开JAV软件包
把里面的“META-INF文件夹”拖出来
用Hhclass软件来删除“META-INF文件”中的“中文”和“？字符”
再把修改好的“META-INF文件”替换JAV软件包中原有的
然后合成时不会再有“???Manifest-Version”提示了！
java里java字符串数组合并成一个数组方法如下：
//方法一 Arrays类
String[] a = {"A","B","C"}
String[] b = {"D","E"}
// List<String>list = Arrays.asList(a) --OK
// List<String>list = Arrays.asList("A","B","C")--OK
// list.add("F")--UnsupportedOperationException
// list.remove("A")--UnsupportedOperationException
// list.set(1,"javaee")--OK (因为是把数组转为集合，其本质还是数组，数组长度固定不变，但内容可以改变)
// 结论：虽然可以把数组转为集合，但是集合长度不能改变
List list = new ArrayList(Arrays.asList(a))
list.addAll(Arrays.asList(b))
String[] str = new String[list.size()]
list.toArray(str)
for(int x=0x<str.lengthx++){
System.out.print(str[x] + " ")
}
//方法二 循环遍历
// 两个数组合并
String[] str1 = {"Hello","world","java"}
String[] str2 = {"Veriable","syntax","interator"}
String[] newStr = new String[str1.length+str2.length]
//newStr = str1数组是引用类型
for(int x=0x<str1.lengthx++){
newStr[x] = str1[x]
}
for(int y=0y<str2.lengthy++){
newStr[str1.length+y]=str2[y]
}
for(int y=0y<newStr.lengthy++){
System.out.println(newStr[y] + " ")
}
// 方法三
String[] str1 = {"Hello","world","java"}
String[] str2 = {"Veriable","syntax","interator"}
int str1Length = str1.length
int str2length = str2.length
str1 = Arrays.copyOf(str1, str1Length+str2length)//数组扩容
System.arraycopy(str2, 0, str1, str1Length, str2length)
System.out.println(Arrays.toString(str1))
