public class While { public void loop() { int x= 0; while ( 1 ) /* Line 6 / { System.out.print("x plus one is " + (x + 1)); / Line 8 */ } } } Which statement is true?

public class While
{
public void loop()
{
int x= 0;
while ( 1 ) /* Line 6 */
{
System.out.print("x plus one is " + (x + 1)); /* Line 8 */
}
}
}

Which statement is true?

[A].	There is a syntax error on line 1.
[B].	There are syntax errors on lines 1 and 6.
[C].	There are syntax errors on lines 1, 6, and 8.
[D].	There is a syntax error on line 6.

Answer: Option D

Explanation:

Using the integer 1 in the while statement, or any other looping or conditional construct for that matter, will result in a compiler error. This is old C Program syntax, not valid Java.

A, B and C are incorrect because line 1 is valid (Java is case sensitive so While is a valid class name). Line 8 is also valid because an equation may be placed in a String operation as shown.

public class While { public void loop() { int x= 0; while ( 1 ) /* Line 6 / { System.out.print("x plus one is " + (x + 1)); / Line 8 */ } } } Which statement is true?
