我已经安装了java,遵循我在SO上找到的所有ubuntu特定建议。但是,就像我javac Program.java
一样,看起来我正在进入一个无限循环。只是打字输入,甚至不能打字离开(即使clt-c不起作用)。
Reverse.java
/**
* This program echos the command-line arguments backwards.
**/
public class Reverse {
public static void main(String[] args) {
// Loop backwards through the array of arguments
for(int i = args.length-1; i >= 0; i--) {
// Loop backwards through the characters in each argument
for(int j=args[i].length()-1; j>=0; j--) {
// Print out character j of argument i.
System.out.print(args[i].charAt(j));
}
System.out.print(" "); // add a space at the end of each argument
}
System.out.println(); // and terminate the line when we're done.
}
}
