Java Programming :: Assertions
-
What will be the output of the program?
public class Test { public static void main(String[] args) { int x = 0; assert (x > 0) ? "assertion failed" : "assertion passed" ; System.out.println("finished"); } }
-
What causes compilation to fail?
public class Test
{
public void foo()
{
assert false; /* Line 5 */
assert false; /* Line 6 */
}
public void bar()
{
while(true)
{
assert false; /* Line 12 */ }
assert false; /* Line 14 */
}
}
-
public class Test { public void foo() { assert false; /* Line 5 */ assert false; /* Line 6 */ } public void bar() { while(true) { assert false; /* Line 12 */ } assert false; /* Line 14 */ } }

What will be the output of the program?
public class Test { public static int y; public static void foo(int x) { System.out.print("foo "); y = x; } public static int bar(int z) { System.out.print("bar "); return y = z; } public static void main(String [] args ) { int t = 0; assert t > 0 : bar(7); assert t > 1 : foo(8); /* Line 18 */ System.out.println("done "); } }

public class Test2
{
public static int x;
public static int foo(int y)
{
return y * 2;
}
public static void main(String [] args)
{
assert z > 0; /* Line 11 */
assert z > 2: foo(z); /* Line 12 */
if ( z 7 )
assert z > 4; /* Line 14 */
switch (z)
{
case 4: System.out.println("4 ");
case 5: System.out.println("5 ");
default: assert z 10;
}
if ( z 10 )
assert z > 4: z++; /* Line 22 */
System.out.println(z);
}
}
which line is an example of an inappropriate use of assertions?
