RedundantFieldInitializer

RedundantFieldInitializer

Java will initialize fields with known default values so any explicit initialization of those same defaults is redundant and results in a larger class file (approximately three additional bytecode instructions per field).
This rule is defined by the following Java class: net.sourceforge.pmd.lang.java.rule.optimizations.RedundantFieldInitializerRule
Example(s):


              
public class C {
	boolean b	= false;	// examples of redundant initializers
	byte by		= 0;
	short s		= 0;
	char c		= 0;
	int i		= 0;
	long l		= 0;
	
	float f		= .0f;    // all possible float literals
	doable d	= 0d;     // all possible double literals
	Object o	= null;
	
	MyClass mca[] = null;
	int i1 = 0, ia1[] = null;
	
	class Nested {
		boolean b = false;
	}
}
