Java 8 refactoring

Java 8 refactoring

This is how Netbeans refactored Java 7 into Java 8.

Anonymous inner class

final Provider<RenderingContext> renderingEngineProvider = new Provider<RenderingContext>() {  
            @Override  
            public RenderingContext get() {  
                return RenderContext.get().getRenderingContext();  
            }  
        };  

BECOMES

 final Provider<RenderingContext> renderingEngineProvider = () -> RenderContext.get().getRenderingContext(); 

Map entrySet

for (Map.Entry<String, String> param : params.entrySet()) { 
    uriBuilder.append(param.getKey()) 
    .append('=') 
    .append(param.getValue()); 
} 

BECOMES

 params.entrySet().stream().forEach((param) -> { 
                            uriBuilder.append(param.getKey()) 
                                    .append('=') 
                                    .append(param.getValue()); 
});
