What will be the output on compiling/running the following code? public class MyThread implements Runnable { String myString = "Yes "; public void run() { this.myString = "No "; } public static void main(String[] args) { MyThread t = new MyThread(); new Thread(t).start(); for (int i=0; i < 10; i++) System.out.print(t.myString); } }

we Can create multiple objects of a single class.

The modulus operator (%) in Java can be used only with variables of integer type.

Declarations must appear at the start of the body of a Java method.

Whenever the "&&" operator is used, such as in: exp1 && exp2 where exp1 and exp2 are boolean expressions, both the boolean expressions are not always evaluated.

What is displayed when the following code is compiled and executed? String s1 = new String("Test"); String s2 = new String("Test"); if (s1==s2) System.out.println("Same"); if (s1.equals(s2)) System.out.println("Equals");

1) What will be the output of the following program?package chapters.chap02;public class Chap02 { public static void main(String[] args) { for (int i=0; i&lt;5; i++){ switch (i){ case 0: System.out.println(&quot;0&quot;); ++i; break; case -1: System.out.println(&quot;-1&quot;); break; case 2: System.out.println(&quot;2&quot;); i++; case 4: System.out.println(&quot;4&quot;); break; } } }}

2) What will be the output of the following program when it is made to run with the options "java scjp5_0.chap07.Ques01 1"package scjp5_0.chap07;public class Ques01 { public static void main(String[] args) { for (int i = 0; i < 2; i ++){ try{ System.out.println(args[i]); }catch(Exception e){} } }}

3) How can you call one constructor from another if a class has multiple constructors

4) What is the result of compiling and running the following code? class VarArgOne { public static void printArgs(String s, Integer ... i, String s) { //line 1 for(int j : i) { //line 2 System.out.print(j + " " + s); //line 3 } } public static void main(String ... args) { //line 4 printArgs("exam", 12, 34, "scjp"); //line 5 } }
