java - renameTo() not working -



java - renameTo() not working -

i need rename file replacing - _ in file name.

suppose if file name ab-9.xml, should ab_9.xml.

renameto() not working me. there other way that? here code:

file replacecheracter(file file) { file oldpath = new file(file.getpath()) string filepath = file.getpath() if(filepath.contains("-")){ string newfilepath = filepath.replace("-", "_") if(oldpath.renameto(newfilepath)) { system.out.println("renamed"); } else { system.out.println("error"); } } homecoming oldpath }

you should consider using java.nio.file package:

final path file = paths.get("path\\to\\your-file.txt"); files.move(file, file.resolvesibling(file.getfilename().tostring().replace("-", "_")));

used handy function path#resolvesibling() sec argument files#move().

explanation:

path#resolvesibling() takes directory path of path object called on, , swaps lastly part (the actual file name) supplied argument (the new, modified file name in case).

using behavior sec argument files#move() result in move source directory , target directory same, renames file.

see the java tutorials - file i/o farther info on this.

java groovy
