原文:https://www . geeksforgeeks . org/char-char value-in-Java-with-examples/
Java . lang . character . charvalue()是 Java 中的内置方法，返回这个字符对象的值。此方法将字符对象转换为其基本数据类型字符。
语法:
public char charValue()
The function does not accepts any parameter.
返回类型:这个方法返回这个对象所表示的原始字符值。
下面的程序说明了 Java.lang.Character.charValue()方法:
程序 1:
// Java program to demonstrate the
// Java.lang.Character.charValue() method
// when the assigned char is a character
import java.lang.*;
public class Gfg1 {
public static void main(String[] args)
{
// Create a character object
Character x = new Character('z');
// assign the primitive value to a character
char ch = x.charValue();
System.out.println("Primitive char value is " + ch);
}
}
Output:
Primitive char value is z
程序 2: 当我们给 x 的值赋任意数字时:
// Java program to demonstrate the
// function when the assigned value is
// a number
import java.lang.*;
public class Gfg {
public static void main(String[] args)
{
// create a Character object x
Character x = new Character('9');
// assign value is a number
// assign the primitive value to a character
char ch = x.charValue();
// print the primitive char value
System.out.println("Primitive char value is " + ch);
}
}
Output:
Primitive char value is 9
