amanda is a tool to strip your java source code to make it naked. This tool is useful to hide solutions in programming exercises.

A file with input:

public int computeSum(int a, int b) {
// STUDENT return 0; // TODO
// BEGIN STRIP
    return a + b; // the solution to hide
// END STRIP
}

Gives as output:

public int computeSum(int a, int b) {
    return 0; // TODO
}
