Answer:</h2>
i. Number of parameters
ii. Type of parameters
<h2>
Explanation:</h2>
When there are two or more constructors, definitely with the same name, in a given class, then the constructors are said to be overloaded. An overloaded constructor appears declared many times in a class but each time with different number of parameters and/or type of parameters.
For example, given a class Test, the following combination of constructors can exist;
i. public Test(int x){
}
ii. public Test(String m){
}
iii. public Test(int a, String b){
}
<em>The following should be noted;</em>
In the case of combination (i) and (ii), the constructors have the same number of parameters but different type of parameter. In other words, they both have 1 parameter but while the first one has a parameter type of <em>int</em>, the second has a parameter type of <em>String</em>.
In the case of combination (ii) and (iii), the constructors have different number of parameters and of course different type of parameters. In other words, the second constructor has 1 parameter of type <em>String</em> while the third constructor has 2 parameters of types <em>int</em> and <em>String</em>.
sorry I was testing something
