Description
|
There are some places we use something like:
new String("xyz")
new Boolean(value)
new Integer(value)
all that causes to create duplicate objects. Refer to Effective Java book [Article 4]. There are a lot of such places in Swing and AWT code. Below are only three of them:
src/windows/classes/sun/awt/windows/WInputMethod.java
javax/swing/plaf/metal/MetalLookAndFeel.java:462: Integer zero = new Integer(0);
com/sun/java/swing/plaf/gtk/GTKStyle.java:854: value = new Integer(16 + 2 * focusLineWidth);
STEPS TO FOLLOW TO REPRODUCE:
Grep for a particular pattern.
