Write all the code within the main method in the TestTruck class below. Implement the following functionality. Construct two Truck objects: one with any make and model you choose and the second object with gas tank capacity 10. If an exception occurs, print the stack trace. Print both Truck objects that were constructed. import java.lang.IllegalArgumentException ; public class TestTruck { public static void main( String[] args ) { // write your code here

How do I remove the space at the end of the result? Code: import java.util.Scanner; public class FinalExamAnswers{ public static void main(String [] args) { manipulateString(); //calls function } //your code here public static void manipulateString() { Scanner sc=new Scanner(System.in); //create Scanner instance System.out.println("Enter a sentence"); String sentence=sc.nextLine(); //input a sentence String[] words=sentence.split(" "); //split the sentence at space and store it in array for(int i=0;i<words.length;i++) //i from 0 to last index { if(i%2==0) //if even index words[i]=words[i].toUpperCase(); //converted to upper case else //if odd index words[i]=words[i].toLowerCase(); //converted to lower case } for(int i=words.length-1;i>=0;i--) //i from last index to 0 {...

JAVA CODE: check output

Please make the code do what the description says.

I have the following code: import java.util.*; import java.io.*; public class GradeBook { publicstaticvoidmain(String[] args)throwsIOException{ // TODO Auto-generated method stub File infile =newFile("students.dat"); Scanner in =newScanner(infile); while(in.hasNext()){ // Read information form file and create a student object and print String name = in.nextLine(); Student student =newStudent(name, in.nextLine()); for(int i =1; i <=4;++i){ student.setQuiz(i, in.nextInt()); } student.setMidtrmExm(in.nextInt()); student.setFinalExm(in.nextInt()); in.nextLine(); // Calculate grade and letter grade; double overallQuizScore=0.0,score=0.0; for(int i=1;i<=student.NUM_QUIZZES;i++) { overallQuizScore+=(student.getQuiz(i)/student.QUIZ_MAX_POINTS)*100; } overallQuizScore = (overallQuizScore/4)*0.30; score =...

Why does this not work

Java provides a mechanism that enables a program to be executed from the command line, as an application. Java runtime execution works on the basis that the class executed must have a: (constructor? inner class? method?) named `main’ that is: (final? static? local?) , public and void. This should take an : (StringBuffer? ArrayList? Array?) of Strings as its only argument. Execution is begun by (calling this method? clicking the BlueJ Run button? selecting this method from the dropdown menu?) . Select the correct answer.
