char 和 int类型的转换

char 如何转化为 int类型

[nightsuns]

casting

for eg:

char a=(int) 100;

[stamp80]

将char强制转换为string，然后再Integer。parseInt。

[qiyongjun2003]

int i=Integer.parseInt(s);

[vampire1129]

int b='a';//b=97
得到a的二进制代码97

看看下面的测试程序，挺有意思：）
但愿对你理解char与int有帮助！

public class TestCast{
private static final char TEST_CHAR = 'A';
public TestCast(){}
public boolean test(String testVer){
System.out.println (testVer + " is a String!");
return true;
}
public boolean test(int testVer){
System.out.println (testVer + " is a int!");
return true;
}
public boolean test(char testVer){
System.out.println (testVer + " is a char!");
return true;
}
public boolean cast(String testVer){
System.out.println (testVer + " can cast to String!");
return true;
}
public boolean cast(int testVer){
System.out.println (testVer + " can cast to int!");
return true;
}
public static void main(String[] args){
TestCast test = new TestCast();
test.test(TEST_CHAR);
test.test(TEST_CHAR + "");
test.cast(TEST_CHAR);
}
}

[网络咖啡]

public class T3{
public static void main(String[] args){
//第一种转换
int i = 0;
char c = 'a';

i = c;

System.out.println(i);

//第二种转换
int j = 0;
char c1 = '1';

j = Integer.parseInt(Character.toString(c1));

System.out.println(j);
}
}

怎么没说运行结果？

Integer.parseInt
