Java – how to set default method parameter values?

See the English answer > does Java support default parameter values? 17

Example: if there is a method

public int doSomething(int arg1,int arg2)
{
//some logic here
    return 0;
}

Can a given method be modified so that it can be called with and without parameters?

Example:

doSomething(param1,param2);
doSomething();

thank you!

Solution

You can do this through method overloading

public int doSomething(int arg1,int arg2)
{
        return 0;
}

public int doSomething()
{
        return doSomething(defaultValue0,defaultValue1);
}

By creating this parameterless method, you allow the user to call the parameterfull method using the default parameters provided in the implementation of the parameterless method This is called overloading the method
