Comparing string to an array of string elements

If I understand you correctly, Write a loop, where iterate multiple string(example array) and equals with src string.

String [] string = new String [10];
...
String src = ..;//src string

for(String string : string){
    if(src.equals(string)){
       //Equal
    }
}

Try using this:

for (int i = 0; i < string.length; i++) {
    if (ch.equals(string[i])) { // ch is the string to compare
    System.out.println("equal");//or whatever your action is
    }
}

EDIT:

If what you are seeking to do is to verify if the searched string appears in the string[i] you can try:

string[0] = "pentagon";
string[1] = "pencil";
string[2] = "pen";
string[3] = "eraser";
string[4] = "penny";
string[5] = "pen";
string[6] = "penguin";
string[7] = "charp";
string[8] = "charpen";
string[9] = "";
String ch = "pen";

Then test if the arrays elements contain the searched string:

for (int i = 0; i < string.length; i++) {
    if (string[i].indexOf(ch) != -1) {
    System.out.println(string[i]+" contains "+ch);
    } else
    System.out.println(string[i]+" doesn't contain "+ch);
}

EDIT 2:

int i=0;
Boolean found=false;
while(i < string.length && !found) {
    if (string[i].indexOf(ch) != -1) {
    found=true;
    }
 i++;
}
if(found){
system.out.println(ch+" is found");
}
