Java在路徑前添加一個字符串

Question

我有以下代碼

var aMyPath = this.path.split("/");
aMyPath.pop();
aMyPath.push(this.getField("Drive").value + ".pdf");
aMyPath.join("/")

返回/test/Data12/Surface/Roy/Geology/Development/Inspect/form/PDF/TEST1111.pdf現在我想在開頭添加另一個 / 以便它看起來//test/Data12/Surface/Roy/Geology/Development/Inspect/form/PDF/TEST1111.pdf

Answer 1

如果我理解正確，你可以寫

String result = "/" + aMyPath.join("/");

甚至

String result = String.format("/%s", aMyPath.join("/"));
