special memory location inside Java memory, more precisely insidePermGen Space. Any time you create a new String object using String literal, JVM first checks String pool and if an
To improve performance, instead of using string concatenation, useStringBuffer.append(). String objects are immutable—they never change after creation. For example, consider the following code: String str = "testing"; str = str + "abc"; The compiler translates this code as: String str = "t...
We will see two programs to reverse a string. First program reverses the given string using recursion and the second program reads the string entered by user and then reverses it. To understand these programs you should have the knowledge of following co
public static void main(String[ ] args) { String s; System.out.println("s is " + s); } } 1. 2. 3. 4. 5. 6. A)The program compiles and runs fine. B)The program has a runtime error because s is not initialized, but it is referenced in the println statement. ...
String reversePalindrome = new String(charArray); System.out.println(reversePalindrome); } } Running the program produces this output: doT saw I was toD To accomplish the string reversal, the program had to convert the string to an array of characters (firstforloop), reverse the array into ...
