Question

我有这个代码从文件中读取并使用模式打印出来。

打印示例：

水果 appeles = 10 bannanas = 5

我如何使用颜色进行打印，因为我想用红色打造苹果，用黄色打造bannanas字样

如何使用颜色打印？我的意思是＆＃34; TipMaterialKamera2＆＃34;使用红色打印，itemMatcherKamera2是否为黄色？

如果您需要使用不同颜色的按钮上的文字，请尝试：

if (myString.equals("TipMaterialKamera2")) {//use switch if you are on jdk 7
    btnKarema2.setForeground(java.awt.Color.RED);
} else if (myString.equals("itemMatcherKamera2")){
    btnKarema2.setForeground(java.awt.Color.YELLOW);
} else {
    btnKarema2.setForeground(java.awt.Color.GREEN);/default
}
