Java 将颜色应用于日历中的特定日期

我已经开发了一个java代码，它以摆动的方式显示日历。。。我希望一些具体的日期是在一个不同的颜色…如何做到这一点…请帮助我。。。 我正在使用setvalueAt函数将日期插入表中。。。 我用了某种\033[31；1m%1$d\033[0m]来改变颜色…但它不起作用

我用某种\033[31；1m%1$d\033[0m]来改变颜色是什么意思？你想改变哪种颜色？意思是\033[31；1mHELLO\033[0m用红色打印HELLO…就像我用红色打印日期一样…你的代码中HELLO在哪里？@AnilB我执行了你的代码，它用浅红色显示sun/sat列，用浅蓝色显示今天的日期。你不是在尝试实现同样的目标吗？不是。我正在处理一个待办事项列表。我想在ch包含的事件颜色与没有事件的事件颜色不同…我正在处理TaskManager项目

 if (column == 0 || column == 6){ //Week-end
                    setBackground(new Color(255, 220, 220));
                }
                else{ //Week
                    setBackground(new Color(255, 255, 255));
                }

if(row == 0 && column == 6)
            setBackground(new java.awt.Color(0, 0, 255));
        else
            setBackground(table.getBackground());
    }
