This quick tutorial demonstrated ways of testing if two Java Lists are equal. Two List implementations are considered equal when they have the same elements in the same order. We studied how to assert that the two Lists are the same or are equal using JUnit, TestNG, AssertJ, and plain Jav...
ArrayList#get,set和remove首先调用rangeCheck方法。此方法不检查索引是否为负数,它只检查索引是否大于或等于数组的长度。 Javadoc解释了原因:如果索引是负数,则数组访问会抛出ArrayIndexOutOfBoundsException。 privatevoidrangeCheck(intindex) {if(index >=size)thrownewIndexOutOfBoundsException(outOfBoundsMsg(index))...
