**1:打开eclipse并进入如下界面
**如下：2.然后在下图第3行开始输入代码
如图：具体代码为public class HelloWorld{public static void main(String[] args){System.out.println(“true,I am a dev,and can program.”);｝｝
3.完成这个步骤方法有很多，下面列举几个例子：
方法二：具体代码：public class HelloWorld{public static void main(String[] args){System.out.print(“true,”);System.out.print(“I”);System.out.print(" am");System.out.print(" a");System.out.print(" dev,");System.out.print(" and");System.out.print(" can");System.out.print(" program.");
方法三：（很麻烦，不介意使用）：具体代码：
public class HelloWorld{public static void main(String[] args){System.out.print(“t”);System.out.print(“r”);System.out.print(“u”);System.out.print(“e”);System.out.print(",");System.out.print(“I”);System.out.print(" “);System.out.print(“a”);System.out.print(“m”);System.out.print(” “);System.out.print(“a”);System.out.print(” “);System.out.print(“d”);System.out.print(“e”);System.out.print(“v”);System.out.print(”,");System.out.print(“a”);System.out.print(“n”);System.out.print(“d”);System.out.print(" “);System.out.print(“c”);System.out.print(“a”);System.out.print(“n”);System.out.print(” “);System.out.print(“p”);System.out.print(“r”);System.out.print(“o”);System.out.print(“g”);System.out.print(“r”);System.out.print(“a”);System.out.print(“m”);System.out.print(”.");}}
