What is the difference between private and public functions ?

What will happen when you attempt to compile and run the following code? (Assume that the code is compiled and run with assertions enabled.)
public class AssertTest

{
public void methodA(int i)
{
assert i >= 0 : methodB();
System.out.println(i);
}

public void methodB()
{
System.out.println(“The value must not be negative”);
}

public static void main(String args[])
{
AssertTest test = new AssertTest();
test.methodA(-10);
}
}

The class AssertionError has “is – a” relationship with these classes:

What is essential in making sure that your loop is not infinite ?

What results from attempting to compile and run the following code?
public class Ternary
{
public static void main(String args[])
{
int a = 5;
System.out.println(“Value is – ” + ((a < 5) ? 9.9 : 9)); } }

In a ‘for’ loop, what section of the loop is not included in the parentheses after “for” ?

What is the result when you compile and run the following code? public class ThrowsDemo { static void throwMethod() { System.out.println(“Inside throwMethod.”); throw new IllegalAccessException(“demo”); } public static void main(String args[]) { try { throwMethod(); } catch (IllegalAccessException e) { System.out.println(“Caught ” + e); } } }

What will happen when you attempt to compile and run the following code?
int Output = 10;
boolean b1 = false;
if((b1 == true) && ((Output += 10) == 20))
{
System.out.println(“We are equal ” + Output);
}
else
{
System.out.println(“Not equal! ” + Output);
}

Following code will result in: int a = 9/0;

Following code will result in: float a = 9/0;

What will happen when you attempt to compile and run the following code snippet?

String str = “Java”;
StringBuffer buffer = new StringBuffer(str);
if(str.equals(buffer))
{
System.out.println(“Both are equal”);
}
else
{
System.out.println(“Both are not equal”);
}

What is the result when you compile and run the following code?
public class Test
{
public void method()
{
for(int i = 0; i < 3; i++) { System.out.print(i); } System.out.print(i); } }

What is the size of a Char?

Following code will result in: int a1 = 5; double a2 = (float)a1;

Following code will result in:

class A {
int b = 1;
public static void main(String [] args) {
System.out.println(“b is ” + b);
}
}

A class can be transient

A class cannot be declared:

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”);

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); } }

What will happen when you attempt to compile and run the following code snippet?
Boolean b = new Boolean(“TRUE”);
if(b.booleanValue())
{
System.out.println(“Yes : ” + b);
}
else
{
System.out.println(“No : ” + b);
}
