Currently i have a method calling String.format()
in Java 5 and it's working perfectly
String.format("%02x", octet) //octet is a int type
However due to some issue we need to deploy this code in a JDK 1.4 environment, and String.format doesn't exists in 1.4.
Anyone knows any alternative way to perform this function?
You could use something like this snippet:
String hexString = Integer.toHexString(octet);
if (hexString.length() < 2) {
hexString = "0" + hexString;
}
您需要使用Integer.toHexString(int)
并自己填充文本。
我想你应该看看Retroweaver ,它允许你在1.4 JVM上部署Java 1.5。
Retrotranslator支持String.format转换为JDK 1.4
