我一直在尝试制作一个程序,该程序将允许我加密用户名和密码并打印结果。我可以使其正常工作,但我想将循环中的字符排序为单个String,以使其更易于管理。有什么建议吗?
System.out.println("\nYour encrypted username is " );
for(char c : namech)
{
int temp = (int)c;
int namecode = 0;
//makes the characters w,x,y,z loops back to the start of the alphabet
if(temp<=90 & temp>=65)
{
namecode = temp+4;
if(namecode == 91)
{
namecode = 65;
}
else if(namecode == 92)
{
namecode = 66;
}
else if(namecode == 93)
{
namecode = 67;
}
else if(namecode == 94)
{
namecode = 68;
}
int i = namecode;
char d = (char)i;
System.out.print(d);
}
最佳答案
我将使用StringBuilder并在加密每个字符时附加它。简单高效的串联。 IE浏览器
StringBuilder sb = new StringBuilder();
for (char c : namech)
{
// ... your code was here
sb.append(d);
}
System.out.println(sb.toString());
