public class Example {public static void main(String[] args) {String str = "Hello";str.concat(" World");System.out.println(str);}}
Question
public class Example {public static void main(String[] args) {String str = "Hello";str.concat(" World");System.out.println(str);}}
Solution
The given code is written in Java.
Step 1: Declare a public class named "Example". Step 2: Inside the class, declare a public static method named "main" that takes an array of strings as an argument. Step 3: Inside the main method, declare a string variable named "str" and assign it the value "Hello". Step 4: Use the "concat" method of the string class to concatenate the string " World" to the "str" variable. Note that the "concat" method does not modify the original string, but returns a new string with the concatenated value. Step 5: Use the "println" method of the "System" class to print the value of the "str" variable to the console. Step 6: Close the main method and the Example class.
When this code is executed, it will print "Hello" to the console, as the "concat" method does not modify the original string.
