Which of the following is true about method parameters in Java?a)Param...
Method Parameters in Java
Parameters in Java methods are used to pass information into a method when it is called. They allow methods to accept input and perform actions based on that input.
Multiple Parameters of the Same Name
In Java, a method can have multiple parameters, and these parameters can have the same name. However, their scope is limited to the method in which they are declared. This means that even if two parameters have the same name, they are treated as separate variables within the method.
For example:
java
public void printInfo(String name, int age, String name) {
System.out.println("Name: " + name);
System.out.println("Age: " + age);
}
In the above example, the method `printInfo` has two parameters with the name `name`, but they refer to different variables within the method.
Therefore, the statement "A method can have multiple parameters of the same name" is true about method parameters in Java.
