Default values ​​for eight basic data types in Java

Use a piece of code to test the default values ​​of 8 basic data types

package dierge;
public class Ceshi {
int a;
double b;
boolean c;
char d;
float f;
byte e;
long h;
short j;
public static void main(String args[]){
Ceshi a=new Ceshi();
System.out.println("整型的默认值是："+a.a);
System.out.println("双精度浮点型的默认值是："+a.b);
System.out.println("布尔型的默认值是："+a.c);
System.out.println("字符型的默认值是："+a.d);
System.out.println("byte的默认值是："+a.e);
System.out.println("单精度浮点型的默认值是："+a.f);
System.out.println("短整型的默认值是："+a.j);
System.out.println("长整型的默认值是："+a.h);
}
}

The running results are as follows:

The default value of integer type is: 0

Double precision The default value of floating point type is: 0.0

The default value of Boolean type is: false

The default value of character type is:

The following conclusions are drawn:

Basic type default value

byte
short
int
long
0L
float
0.0f
double
0.0d
char
'\u0000'
boolean
false

The above are the default values ​​​​of the eight basic data types in Java introduced by the editor. I hope it will be helpful to you. Everyone is helpful.
