varinit.java

java课件及例程有一些PPT及一些例程

public class VarInit{
    public static void main(String[] args){
        int i = 34;
        long k;
        float f = 4.67f;
        double d = 3.2e5;
        char a = '7';
        a = '\u0037';
        k = 9870;
        boolean b = false;
        //显示上面定义的变量值
        System.out.println("b = "＋b);
        System.out.println("i = "＋i);
        System.out.println("k = "＋k);
        System.out.println("f = "＋f);
        System.out.println("d = "＋d);
        System.out.println("a = "＋a);

    }
