Answer 1

Answer:

b) Plus sign

Explanation:

The plus sign or addition operator (+) accomplishes concatenation. This is a greatly used in the Java's output Statement to combine values coming from different data types into a formatted output

consider the code snippet below  which uses concatenation to output information about an individual

public class Name {

   public static void main(String[] args) {

   int age =18;

   String name = "John";

       System.out.println("His name is "+name +" and his age is "+age);

   }

}

The + operator has been used to concatenate the int value age and the String value stored in name to the output
