Introduce Explaining Variable
From CSSEMediaWiki
If you have a complicated expression put them into temporary variables that explain what they do. This can help make code easier to read and understand.
if ( (platform.toUpperCase().indexOf("MAC") > -1) && (browser.toUpperCase().indexOf("IE") > -1) && wasInitialized() && resize > 0 ) { // do something }
final boolean isMacOs = platform.toUpperCase().indexOf("MAC") > -1;<br> final boolean isIEBrowser = browser.toUpperCase().indexOf("IE") > -1;<br> final boolean wasResized = resize > 0;<br><br> if (isMacOs && isIEBrowser && wasInitialized() && wasResized) { // do something }
