public class MyTest1 {
public static void main(String[] args) {
String str[] = {"abcdefgbc","bvc","ab"};
String substr = "bc";
for(int i=0;i<str.length;i++)
if(str[i].equals(substr)){
System.out.println("存在，且位于数组第"+(i+1)+"个位置");
break;
}
else
if(i==str.length-1)System.out.println("不存在");
}
}

public static int compareStr(String str,String x[]){
int suffix=0;//记录字符串数组的下标
for(int i=0;i<x.length;i++){
if(str==x[i])
suffix=i+1;
}
return suffix;
}
public static void main(String[]agrs ){
String [] ken={"kin","zuo","kin","hen","long","ah","king","aj "};
if(Test.compareStr("king",ken)!=0)
System.out.println(Test.compareStr("king",ken));
else System.out.println("不存在匹配");
}
}
