Split字符串分拆

public static void main(String[] args) {

    String str = "sh -c 'ls / -lh'";
    char[] dataArray = str.toCharArray();
    List<String> result = new ArrayList<>();
    int pos = 0;
    boolean symbol = false;
    for(int i=-0; i<dataArray.length;i++){
        if(dataArray[i]=='\'' || dataArray[i]=='\"'){
            if(symbol){
                symbol = false;
            }else{
                symbol = true;
            }
        }else if(dataArray[i]==' ' && !symbol){
            result.add(new String(dataArray,pos,i-pos));
            pos = i+1;
        }
    }
    if(pos<dataArray.length-1){
        result.add(new String(dataArray,pos,dataArray.length-pos));
    }
    System.out.println();
}

需要一个分词器的实现， 没考虑边缘case和转义，可以尝试自己加下:)

public static void main(String[] args) {
    String input = "sh -c 'ls / -lh'";
    
    int begin=0;
    boolean flag = false;
    
    List result = new ArrayList();
    
    for(int i=0;i<input.length()+1;i++) {
        
        char c;
        if (i>=input.length()) {
            c=' ';
        } else {
            c = input.charAt(i);
        }
        
        switch (c) {
        case ' ':
            if (!flag) {
                if(begin != i) {
                    result.add(input.substring(begin, i));
                }
                begin=i+1;
            }
            break;
        case '\'':
            if(flag) {
                flag = false;
                result.add(input.substring(begin, i));
            } else {
                flag = true;
                if(begin != i) {
                    result.add(input.substring(begin, i));
                }
            }
            begin=i+1;
            break;
        default:
            break;
        }
        
    }
    
    System.out.println("result = " + result);

}

每搜索到一个空格,就把前面的字符串加到数组就可以吧.
