With Clojure, you can mostly ignore Java's syntax until and unless you want or need to write a Java class to call from Clojure for some reason.
But knowing some of the major parts of the standard Java class library (particularly java.lang, java.math, java.util, java.util.concurrent, awt.*, and javax.swing) is useful if you're doing much interop, and the Java classes that are common Clojure literal datatypes have additional operations available through interop (assorted String operations; java.math.BigDecimal.scaleByPowerOfTen(exponent); etc.) Knowing some things about the JVM will also come in handy.
