Given string inputStr on one line and integers idx1 and idx2 on a second line, output "Match found" if the character at index idx1 of inputStr is equal to the character at index idx2. Otherwise, output "Match not found". End with a newline. Ex: If the input is: eerie 4 1 then the output is: Match found Note: Assume the length of string inputStr is greater than or equal to both idx1 and idx2.

Java - How can I output the following statement as a single line with a newline? Program below. import java.util.Scanner; public class LabProgram { public static void main(String[] args) { Scanner sc = new Scanner(System.in); int n = sc.nextInt(); if(n>=11 && n<=100) { while(n>=11 && n<=100) { System.out.print(n+ " "); (the problem line. When I use System.out.println, it makes the line vertical when I want it horizontal.) if(n ==11||n==22||n==33||n==44||n==55||n==66||n==77||n==88||n==99) break; n--; } } else System.out.println("Input must be 11-100"); }}
Fix the code so it runs. Take note of what errors are generated by the compiler. What do these errors mean? How do they help you find and fix the errors? import java.util.Scanner; public class Main {public static void main(String[] args) { int numOfBooks = 130;char bookStoreAns; do {System.out.println("Are you at the book store? (y/n)");bookStoreAns = scnr.next().charAt(0);boolean atBookStore; if (bookStoreAns == 'y') {atBookStore = true;} else if (bookStoreAns == 'n') {atBookStore = false;}} while (bookStoreAns != 'y' && bookStoreAns != 'n'); if (atBookStore) {numOfBooks += 4;} System.out.println("I have " + numOfBooks + " books."); }} Can anyone fix this code in Java?
