If statement isnt working even when i set a boolean to automatically be false

grass.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent arg0) {
    pm = false;
    if(pm=false){
    drawGrassBlock(x1, y, Color.green, size, size2);
    }
    }
});

This is my code and for whatever reason the if statement does nothing....i set the boolean to be false and told it to print a string when inside the if statement but the console wont return anything which means its not properly "getting inside". I told it to print the value of the boolean and its printing false so please help!

That is an assignment within the if, not an equality comparision. From section 15.26 Assignment Operators of the Java Language Specification:

At run time, the result of the assignment expression is the value of the variable after the assignment has occurred.

meaning the result of pm = false is always false, so the if branch is never entered.

Change to:

if (false == pm) // or if (!pm)

Do

if(pm == false)

instead of 

if(pm = false)

Using single = will set pm to false
Using double == will compare pm with false
