除了使用String类的format方法,我们还可以使用StringBuilder类的append方法来实现字符串的右侧补0。具体实现如下: publicclassStringPaddingExample{publicstaticvoidmain(String[]args){StringoriginalString="123";inttargetLength=6;StringBuilderpaddedString=newStringBuilder(originalString);while(paddedString.length()<targetLe...
The format string is a String which may contain fixed text and one or more embedded format specifiers. Consider the following example: <blockquote>text/java 复制 Calendar c = ...; String s = String.format("Duke's Birthday: %1$tm %1$te,%1$tY", c); </blockquote>...

SpringLayout是这种情况的自然选择。几个教程示例中使用的SpringUtilities类定义了一个makeCompactGrid方法,让您可以轻松地对齐多行和多列的组件。 场景:您有一个包含许多组件的复杂布局。 考虑使用非常灵活的布局管理器,如GridBagLayout或SpringLayout,或将组件分组到一个或多个JPanel中以简化布局。如果采用后一种方法,...
