False. Methods in a class can have the same name as long as they have a different signature. You cannot duplicate method code inside a class but you can always have methods that have the same name but a different signature.
Ex: Here I have created two methods in a class that have the same name "sum" but have a different argument types, and return types and hence perfectly allowable in a java class.
Public class PolymorphismExample {
public int sum(int a, int b){
return a + b;
}
public double sum (double a, double b){
return a + b;
}
}
