是否可以使用以下命令替换String中的特定数字:
c:\> RunDLL32.exe URLMon.dll,URLDownloadToFIle 0,"http://www.example.com/file.pdf" "c:\\MyName\\Downloads\\",0
我尝试过这样做,但似乎没有用。有没有动态的方法可以让我使用整数?
以下是代码:
string.replace(4 + "", "FOUR");
当我打印它时,我得到这样的东西:
public void generateData(String text) {
for (int i = 0; i < array.size(); ++i) {
text.replace(array.get(i).number, "HELLO WORLD");
}
System.out.println("T: " + text);
}

它以各种形式运行良好。
public static void main(String[] args) {
test(4, "FOUR", "");
test(4, "FOUR", "Hello");
test(4, "FOUR", "4");
test(4, "FOUR", "1 2 3 4 5 6");
test(4, "FOUR", "123456");
test(4, "FOUR", "Test43");
}
private static void test(int num, String numText, String string) {
System.out.println("\"" + string + "\" -> \"" + string.replace(num + "", numText) + "\"" +
" = \"" + string.replace("" + num, numText) + "\"" +
" = \"" + string.replace(String.valueOf(num), numText) + "\"");
}
输出是:
"" -> "" = "" = ""
"Hello" -> "Hello" = "Hello" = "Hello"
"4" -> "FOUR" = "FOUR" = "FOUR"
"1 2 3 4 5 6" -> "1 2 3 FOUR 5 6" = "1 2 3 FOUR 5 6" = "1 2 3 FOUR 5 6"
"123456" -> "123FOUR56" = "123FOUR56" = "123FOUR56"
"Test43" -> "TestFOUR3" = "TestFOUR3" = "TestFOUR3"

您需要将int
转换为String
,因为String.replace()
需要char
或CharSequence
(String
的超类int
1}})。 不接受Integer.toString()
参数。
执行您要求的最明确的方法是使用public void generateData(String text) {
for (int i = 0; i < array.size(); ++i) {
text=text.replace(Integer.toString(array.get(i).number), "HELLO WORLD");
}
System.out.println("T: " + text);
}
进行投射。像这样:
template: '<a href="{{ link }}" target="_blank"><img src="{{ image }}" /><div class="likes">♥ {{ likes }}</div></a>'
