//Java中的八种基本数据类型
//1、整型
int a = 12;
int b;
b = 19;
int c = a + b;
System.out.println(c);
byte b1 = 23;
System.out.println(b1);
short s1 = 56;
System.out.println(s1);
long l1 = 109;
System.out.println(l1);
//2、浮点型
float f1 = (float) 2.3;
System.out.println(f1);
double d1 = 3.7;
System.out.println(d1);
//3、字符型
char c1 = 'a';
System.out.println(c1);
//4、布尔型
boolean bool1 = true;
boolean bool2 = false;
System.out.println(bool1);
System.out.println(bool2);
System.out.println(a);

}
输出结果：
31 23 56 109 2.3 3.7 a true false 12
