判断一个字符串是否是另外一个字符串的子串

package Interview;
public class SubString {
public static void main(String args[])
{
System.out.println(SubString.judge("sddddgdgassdg", "ss"));
}

public static boolean judge(String s1,String s2)
{
char[] s1char= s1.toCharArray();
char[] s2char = s2.toCharArray();
for(int i = 0;i {
boolean temp = true;
for(int j = 0;j {
if(s1char[i+j]!=s2char[j])
{
temp = false;
break;
}
}
if(temp)
{
return true;
}
}
return false;
}

}

运行结果如下图
