In Java programming, theIntegerclass is used to wrap a value of the primitive typeintin an object. In Java 8, theIntegerclass introduced a useful method calledrange, which creates a sequential range of integers. UsingrangeMethod Therangemethod in theIntegerclass allows you to create a range o...
我们可以使用Java的Range类和一个循环来解决这个问题。以下是一个示例代码: importjava.util.Iterator;publicclassRange<Integer>implementsIterable<Integer>{privateintstart;privateintend;publicRange(intstart,intend){this.start=start;this.end=end;}@OverridepublicIterator<Integer>iterator(){returnnewRangeIterator(st...
Range<Integer> greaterThanTen = Range.greaterThan(10); // 大于10 Range<Integer> atMostFive = Range.atMost(5); // 小于等于5 6. 离散域范围 Range还支持离散域的概念。比如,咱们可以获得一个范围内所有整数的集合: Range<Integer> oneToFive = Range.closed(1, 5); Set<Integer> numbers = Contig...
Range<Integer>closedRange=Range.closed(1,5);// 包括1和5booleancontains1=closedRange.contains(1);// 返回trueRange<Integer>openRange=Range.open(1,5);// 不包括1和5booleancontains1InOpen=openRange.contains(1);// 返回false 2. 处理边界值 处理边界值是Range使用中的一个关键点。特别是在数据过滤...
在处理数据库操作时，我们经常需要向数据库发送SQL语句并执行相应的操作。然而，在使用PGJDBC进行操作时，可能会遇到“Tried to send an out-of-range integer as a 2-byte value: 125000”的错误，这是由于参数个数超限导致的。本文将详细解析此问题的解决方法。在某些特定场景下，如批量INSERT操作时...
