java中String的练习

String的练习

需求：去除一个字符串中相邻重复字符
举例：abbddAffeeEddcccwceaa
输出结果：abdAfeEdcwcea

import java.util.Arrays;

public class TestDemo9 {
	public static void main(String[] args) {
		String str = "abbddAffeeEddcccwceaa";
		char[] array = str.toCharArray();
		char[] arr1 = new char[str.length()];
		int i = 0;
		int j = 0;
		char temp = ' ';
		while(i<array.length) {
			char c1 = array[i];
			if(i!=0 && c1 == temp) {
				i++;
				continue;
			}else {
				arr1[j] = c1;
				j++;
				i++;
				temp = c1;
			}
		}
		System.out.println(Arrays.toString(arr1));
	}

}

运行结果：
