it waits until more data is available.
private void synchronized waitForData()
{ // (1)
try { // (2)
wait(); // (3)
} catch (InterruptedException ex) { // (4)
}}
Another Thread, executingAmethod in
another object C, needs to wake up
Thread A. Assuming that object C has
references to bothAand B, select all of
the following code fragments that
would cause ThreadAto exit the
wait ForData method.​

public void increment()

{

i++;

}

public int getValue()

{

return i;

}

}

class GfG

{

public static void main (String[] args)
