Methods of StringBuilder class

The StringBuilder class can be used to create mutable strings. The methods defined in the StringBuilder class are widely used to manipulate and concatenate strings. It is a non-synchronized class which has public methods that can be accessed by multiple threads. It is not thread-safe.

public static String pancakeScramble(String text) This nifty little problem is taken from the excellent Wolfram Challenges problem site where you can also see examples of what the result should be for various arguments. Given a text string, construct a new string by reversing its first two characters, then reversing the first three characters of that, and so on, until the last round where you reverse your entire current string.This problem is an exercise in Java string manipulation. For some mysterious reason, the Java String type does not come with a reverse method. The canonical way to reverse a Java string str is to first convert it to mutable StringBuilder, reverse its contents, and convert the result back to an immutable string, that is,str = new StringBuilder(str).reverse().toString(); Here's the tester it must pass: @Test public void testPancakeScramble() throws IOException {// Explicit test casesassertEquals("", P2J3.pancakeScramble(""));assertEquals("alu",…

Consider the following application. Identify and correct any syntactic errors or omissions by rewriting the line number and the corrected line. Note: There are 8 lines with errors. Each line may have multiple errors. Here’s an example (here, the error is on line 2, the correction is in bold – int x = 0;): 01 public static void main(String[] args){ 02 int x = '0'; 02 int x = 0; 03 int y + x = 7 03 int y = x + 7; 04 } 01 public Class Average; 02 { 03 public void main(String [] args) 04 { 05 double sc = (70, 75, 90, 83, 85, 97, 82, 79, 94, 87; 06 double me su = 0.0 07 for (int k = 0; k < sc.length(); k++); 08 su += sc[ ]; 09 double me = su/sc.length() 10 System.Out.printf("Output: %.2f" + me); 11 } 12 } What value of the variable me will be printed in line 10?
In C++ Find the five errors. For each error, state the line number, explain the error and show a correction. #include<iostream> #include<iomanip> using namespace std; class colorCode { public: void setRGB(int); //accepts an int parameter and sets the RGB to the value of the parameter void setName(string);//accepts a string parameter and sets the name of the object to the value of the parameter string getName() const;//returns the name of the object int getRGB() const;//returns the RGB of the object void changeColor();// adds 10 to the RGB value private: string name; int RGB; } int main() { colorCode paintCans[10]; int i; for (i = 0; i < 10; i++){ paintCans.setRGB[i] = 0;} paintCans[5].setName(GREEN); paintCan[5].setRGB(192000); cout << paintCans[5].getName << ' ' << paintCans[5].getRGB() << endl; return 0; }
