两层for循环的执行过程 为了更直观地理解两层for循环的执行过程,我们可以通过序列图来展示。下面是使用mermaid语法中的sequenceDiagram标识的两层for循环执行过程: mnOperationjimnOperationjiloop[InnerLoop]loop[OuterLoop]初始化i=0i<n初始化j=0j<m执行需要重复的操作j++i++ 在上述序列图中,表示了两层for循环的...

As mentioned in syntax, theinitialization, termination, and increment are optional parts, that can be controlled from other places. Or the for loop might not have all of them. For example, we can rewrite the previous example as below. We have taken out thecounterinitialization before the loop...
do-while循环称为后测试循环(posttest loop),因为在循环体执行之后,要检测一下这个条件. 在循环中可以使用关键字break和continue. 关键字break立即终止包含break的最内层循环. 关键字continue只是终止当前迭代. packagewelcome;/** 使用嵌套for循环打印一个乘法表*/publicclassMultiplicationTable {publicstaticvoidmain(St...

for (int i=0; i<100_000; i++) { sum = sum.add(c); } TheBigDecimalnumber is immutable, therefore a new object is always assigned to the sum variable in every loop. $ java Main.java 146000.00 In this example, we get the precise value. ...

The first print() function call is part of the for loop block. Line 9: This second dedented print() function call isn’t part of the for loop block. You might have noticed that a colon (:) at the end of a line introduces a new sub-block of code, which should be indented one ...
