Nice code snippet. But it does not work with boolean properties.
This is how you can add boolean props:
for (int i = 0; i < methods.length; i++) {
method = methods[i];
final String methodName = method.getName();
final boolean isBooleanProp = methodName.startsWith(“is”);
if ((methodName.startsWith(“get”) || isBooleanProp) && !method.getName().startsWith(“getClass”)) {
buffer.append(method.getName().replaceAll(isBooleanProp ? “is” : “get”, “”));
buffer.append(” = “);
Object[] params = null;
try {
buffer.append(method.invoke(this, params));
} catch (Exception e) {
buffer.append(” “);
}
buffer.append(lineSeaparator);
}
}

It prints the values too. We are invoking the getter method using the reflection
method.invoke(this, params)
which returns the value.

Does this method print only the variable names or variable names + values?

From the code, I think it prints only variable names. Is it correct?
