This can be done in two ways.这可以通过两种方式完成。
JLabel Horizontal Alignment JLabel 水平对齐
You can use the JLabel constructor :您可以使用JLabel 构造函数：
JLabel(String text, int horizontalAlignment)
To align to the right:要向右对齐：
JLabel label = new JLabel("Telephone", SwingConstants.RIGHT);
JLabel also has setHorizontalAlignment : JLabel也有setHorizontalAlignment ：
label.setHorizontalAlignment(SwingConstants.RIGHT);
This assumes the component takes up the whole width in the container.这假设组件占据了容器的整个宽度。
Using Layout使用布局
A different approach is to use the layout to actually align the component to the right, whilst ensuring they do not take the whole width.另一种方法是使用布局将组件实际对齐到右侧，同时确保它们不会占据整个宽度。 Here is an example with BoxLayout :这是一个BoxLayout的例子：
Box box = Box.createVerticalBox();
JLabel label1 = new JLabel("test1, the beginning");
label1.setAlignmentX(Component.RIGHT_ALIGNMENT);
box.add(label1);
JLabel label2 = new JLabel("test2, some more");
label2.setAlignmentX(Component.RIGHT_ALIGNMENT);
box.add(label2);
JLabel label3 = new JLabel("test3");
label3.setAlignmentX(Component.RIGHT_ALIGNMENT);
box.add(label3);
add(box);

To me, it seems as if your actual intention is to put different words on different lines.在我看来，您的实际意图似乎是将不同的词放在不同的行上。 But let me answer your first question:但让我回答你的第一个问题：
JLabel lab=new JLabel("text");
lab.setHorizontalAlignment(SwingConstants.LEFT);
And if you have an image:如果你有一张图片：
JLabel lab=new Jlabel("text");
lab.setIcon(new ImageIcon("path//img.png"));
lab.setHorizontalTextPosition(SwingConstants.LEFT);
But, I believe you want to make the label such that there are only 2 words on 1 line.但是，我相信您想让标签在 1 行中只有 2 个单词。
In that case try this:在这种情况下，试试这个：
String urText="<html>You can<br>use basic HTML<br>in Swing<br> components,"
+"Hope<br> I helped!";
JLabel lac=new JLabel(urText);
lac.setAlignmentX(Component.RIGHT_ALIGNMENT);
