难于理解的复杂表达式

if ((platform.toUpperCase().indexOf("MAC") > -1) &&(brower.toUpperCase().indexOf("IE") > -1) &&wasInitialized && resize > 0) {// do something
}

重构后

final boolean isMacOS = platform.toUpperCase().indexOf("MAC") > -1;
final boolean isIEBrowser = brower.toUpperCase().indexOf("IE") > -1;
final boolean wasResized = resize > 0;
if (isMacOS && isIEBrowser && wasInitialized() && wasResized) {// do something
}
