What is the missing keyword in the program below?
public class Batman {
public static int minFunction(int n1, int n2) {
int min;
if (n1 > n2)
min = n2;
else
min = n1;
return min; //This is the value that will be returned from the minFunction method.
//The value after the keyword return must match the return type from the method header. Ours is OK because they are both int.
} // end the public method named minFunction
} // end the public class of Batman
public class MyClass {
public static void main(String args[]) {
Batman Bruce = ___ Batman();{ <------ missing keyword?
int BatmanRounds = Batman.minFunction(3,4); {
System.out.println(BatmanRounds);
}//end the minFunction
}//end the Bruce Batman object
}//end main method
}// end of MyClass class

Explain in detail what the code below does: public class MyClass { public static void main(String args[]) { System.out.println(isUniqueChars("something")); } public static boolean isUniqueChars(String str) { int checker = 0; for (int i = 0; i < str.length(); ++i) { int val = str.charAt(i) - 'a'; if ((checker & (1 << val)) > 0) return false; checker |= (1 << val); } return true;...
Complete the following Java program by writing the missing methods. public class 02 { public static void main(String[] args) { Scanner scan = new Scanner(System.in); System.out.println("Enter a number: int n = scan.nextInt(); if (isOdd (n)) { //Print n to 1 System.out.println("Print all numbers from "+n+" to 1"); printNumToOne (n); } else { System.out.println(n + " is //End of main()
In the following program: public class Problem2{ public static int sample(int x, int y){ int z; ...... } public static void main(String[] args) { int a, b; ...... sample(a,b); } } (1) What is the return type of sample? (2) What are the local variables of sample? (3) What are the parameters of sample? (4) What are the arguments of sample? (5) Is sample a per-object method? Or a per-class method? (6) Is sample a public method, or private method?
(How do I remove the STATIC ArrayList from the public class Accounts, and move it to the MAIN?) import java.util.ArrayList; import java.util.Scanner; public class Accounts { static ArrayList<String> accounts = new ArrayList<>(); static Scanner scanner = new Scanner(System.in); public static void main(String[] args) { Scanner scanner = new Scanner(System.in); int option = 0; do { System.out.println("0->quit\n1->add\n2->overwirte\n3->remove\n4->display"); System.out.println("Enter your option"); option = scanner.nextInt(); if (option == 0) { break; } else if (option == 1) { add(); } else...

Write a program that will check a Java file for syntax errors. The program will ask for an input-file name and output-file name and will then copy all the code from the Java input file to the Java output file, but with the following changes: 1. Any syntax error found in the Java input file will be corrected: a. Missing semicolon b. Missing compound statements (curly braces) c. All comments have to start with // and end with a period....
What output is produced by the following program? public class MysteryNums public static void main(String[] args) - int x = 12; int y = x - 3; 3, sentence (y, x + y); . public static void sentence (int numi, int num2) { 4: System.out.println(num1 + " + num2);
Analyze the following code: public class Test { private int t; public static void main(String[] args) { int x; System.out.println(t); } } The variable t is private and therefore cannot be accessed in the main method. The program compiles and runs fine. t is non-static and it cannot be referenced in a static context in the main method. The variablet is not initialized and therefore causes errors. The variable x is not initialized and therefore causes errors.
