• String sinfida equals usulining maxsus xoli boʼlgan usullar guruxi mavjud. Bir satrdagi ostki satrni ikkinchi satrdagi ostki satr bilan solishtirish uchun regionMatches usulidan foydalaniladi. Ostki satr parametr sifatida uzatilgan fragment bilan boshlanishini aniqlash uchun startsWith usulidan foydalaniladi. Satr oxiri parametr bilan bir xilligini tekshirish uchun endsWith usuli ishlatiladi

• Satrlarni solishtirishda equals usuli va operator == turli tekshirishni amalga oshiradi. Аgar equal usuli simvollarni satr ichida solishtirsa operator == obʼektlarga koʼrsatkichlarni solishtiradi va ular bir xil obʼektga ilova qilayotganligini tekshiradi. Quyidagi misolda satrlar bir xil boʼlgani bilan, turli obʼektlar boʼlgani uchun equals va == turli natijalarni beradi.
