datatypetest.java

这个是JAVA方面的联系程序

public class DataTypeTest {
	public static void main(String[] args) {
		boolean boo = false;
		char ch = 'A';
		byte b = 127;
		short sh = 2344;
		int x = 432223;
		long l = 32322323;
		float f = 0.32f;  //(float)0.32  , 0.32f
		double d = 3.14;
		
		System.out.println(boo);
		System.out.println(ch);
		System.out.println(b);
		System.out.println(sh);
		System.out.println(x);
		System.out.println(l);
		System.out.println(f);
		System.out.println(d);
		
	}
}
