Question

Examine this code:

String str = ""One Fine Day"" ;
String val = str.substring(4) ;
System.out.println( val );
What does the fragment print?

Answer 1

The given Java code snippet will print "Fine Day" after executing the substring method starting from index 4 of the string "One Fine Day".

Step-by-step explanation:

The code provided contains a call to the substring method of a String object in Java. The substring method is used to extract a part of a string starting from the index specified as the method argument until the end of the string. In the given code, str.substring(4) is called, which will extract the substring starting from the 5th character (since indices in Java are 0-based) of the String stored in the variable str. The str variable contains the text "One Fine Day", so the output after extracting the substring from index 4 would be "Fine Day". Therefore, when the code is executed, it will print "Fine Day".

The given code snippet is written in the Java programming language. It declares a string variable called 'str' and assigns it the value 'One Fine Day'. Then, another string variable called 'val' is declared and assigned the value obtained by taking a substring of 'str' starting from the index 4. The substring function in Java returns a new string that includes characters from the specified index to the end of the original string.

In this case, the substring 'Fine Day' is assigned to 'val'. Finally, the value of 'val' is printed to the console using the 'System.out.println()' method. Therefore, the fragment will print 'Fine Day'.
