将this is a test 转化为This Is A Test

public class Demon{

public static void main(String[] args) {

String str = "this is a man";

System.out.print("原句型："+str);

char c[] = new char[str.length()];

str.getChars(0, str.length(), c, 0);

if (c[0] >= 'a' && c[0] <= 'z') {

c[0] = (char) (c[0] - 32);

}

for (int i = 1; i <= c.length - 1; i++) {

if (c[i] == ' ') {

c[i + 1] = (char) (c[i + 1] - 32);

}

}

str = new String(c);

System.out.print("转换后的句型："+str);

}

}
